During bacterial cell division, FtsZ—a prokaryotic homologue of the eukaryotic protein tubulin—polymerizes into treadmilling filaments that further organize into a cytoskeletal ring. In vitro, FtsZ filaments can form dynamic chiral assemblies. However, how the active and passive properties of individual filaments relate to these large-scale self-organized structures remains poorly understood. Here we connect single-filament properties with the mesoscopic scale by combining minimal active matter simulations and biochemical reconstitution experiments. We show that the density and flexibility of active chiral filaments define their global order. At intermediate densities, curved, flexible filaments organize into chiral rings and polar bands. An effectively nematic organization dominates for high densities and for straight, mutant filaments with increased rigidity. Our predicted phase diagram quantitatively captures these features, demonstrating how the flexibility, density and chirality of the active filaments affect their collective behaviour. Our findings shed light on the fundamental properties of active chiral matter and explain how treadmilling FtsZ filaments organize during bacterial cell division.","lang":"eng"}],"date_updated":"2026-06-10T09:41:11Z","intvolume":"        19","department":[{"_id":"JoDa"},{"_id":"EdHa"},{"_id":"MaLo"},{"_id":"GradSch"}],"scopus_import":"1","article_type":"original","_id":"13314","article_processing_charge":"Yes (in subscription journal)","oa_version":"Published Version","day":"01","ddc":["530"],"quality_controlled":"1","citation":{"chicago":"Dunajova, Zuzana, Batirtze Prats Mateu, Philipp Radler, Keesiang Lim, Dörte Brandis, Philipp Velicky, Johann G Danzl, et al. “Chiral and Nematic Phases of Flexible Active Filaments.” <i>Nature Physics</i>.

Such changes result from tension dynamics at cell contacts or cellular jamming. Yet, in many cases, the cellular mechanisms controlling the physical state of growing tissues are unclear. We found that at early developmental stages, the epithelium in the developing mouse spinal cord maintains both high junctional tension and high fluidity. This is achieved via a mechanism in which interkinetic nuclear movements generate cell area dynamics that drive extensive cell rearrangements. Over time, the cell proliferation rate declines, effectively solidifying the tissue. Thus, unlike well-studied jamming transitions, the solidification uncovered here resembles a glass transition that depends on the dynamical stresses generated by proliferation and differentiation. Our finding that the fluidity of developing epithelia is linked to interkinetic nuclear movements and the dynamics of growth is likely to be relevant to multiple developing tissues.","lang":"eng"}],"scopus_import":"1","article_type":"original","intvolume":"        19","department":[{"_id":"EdHa"},{"_id":"AnKi"}],"day":"01","_id":"12837","article_processing_charge":"No","oa_version":"Published Version","quality_controlled":"1","citation":{"ama":"Bocanegra L, Singh A, Hannezo EB, Zagórski MP, Kicheva A.

Here we report a study of the transport and microwave response of Josephson arrays with interactions exceeding this level. Contrary to expectations, we observe that the array resistance drops dramatically as the temperature is decreased—reminiscent of superconducting behaviour—and then saturates at low temperature. Applying a magnetic field, we eventually observe a transition to a highly resistive regime. These observations can be understood within a theoretical picture that accounts for the effect of thermal fluctuations on the insulating phase. On the basis of the agreement between experiment and theory, we suggest that apparent superconductivity in our Josephson arrays arises from melting the zero-temperature insulator."}],"project":[{"_id":"0aa3608a-070f-11eb-9043-e9cd8a2bd931","grant_number":"P33692","name":"Cavity electromechanics across a quantum phase transition"},{"_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411","call_identifier":"H2020"},{"name":"Protected states of quantum matter","_id":"eb9b30ac-77a9-11ec-83b8-871f581d53d2"}],"external_id":{"isi":["001054563800006"]},"date_created":"2023-08-11T07:41:17Z","title":"Superconductivity from a melted insulator in Josephson junction arrays","author":[{"full_name":"Mukhopadhyay, Soham","id":"FDE60288-A89D-11E9-947F-1AF6E5697425","orcid":"0000-0001-5263-5559","first_name":"Soham","last_name":"Mukhopadhyay"},{"orcid":"0000-0002-0672-9295","last_name":"Senior","first_name":"Jorden L","id":"5479D234-2D30-11EA-89CC-40953DDC885E","full_name":"Senior, Jorden L"},{"last_name":"Saez Mollejo","first_name":"Jaime","id":"e0390f72-f6e0-11ea-865d-862393336714","full_name":"Saez Mollejo, Jaime"},{"full_name":"Puglia, Denise","id":"4D495994-AE37-11E9-AC72-31CAE5697425","first_name":"Denise","last_name":"Puglia","orcid":"0000-0003-1144-2763"},{"first_name":"Martin","last_name":"Zemlicka","orcid":"0009-0005-0878-3032","id":"2DCF8DE6-F248-11E8-B48F-1D18A9856A87","full_name":"Zemlicka, Martin"},{"full_name":"Fink, Johannes M","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8112-028X","last_name":"Fink","first_name":"Johannes M"},{"first_name":"Andrew P","last_name":"Higginbotham","orcid":"0000-0003-2607-2363","id":"4AD6785A-F248-11E8-B48F-1D18A9856A87","full_name":"Higginbotham, Andrew P"}],"day":"01","_id":"14032","oa_version":"Published Version","article_processing_charge":"Yes (in subscription journal)","scopus_import":"1","article_type":"original","intvolume":"        19","department":[{"_id":"GradSch"},{"_id":"AnHi"},{"_id":"JoFi"}],"acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"NanoFab"}],"publisher":"Springer Nature","citation":{"chicago":"Mukhopadhyay, Soham, Jorden L Senior, Jaime Saez Mollejo, Denise Puglia, Martin Zemlicka, Johannes M Fink, and Andrew P Higginbotham. “Superconductivity from a Melted Insulator in Josephson Junction Arrays.” <i>Nature Physics</i>.

However, how these processes are coordinated, and how tissue patterning is preserved despite the cellular flows occurring during morphogenesis, remains poorly understood. Gastrulation is a crucial embryonic stage that involves both patterning and internalization of the mesendoderm germ layer tissue. Here we show that, in zebrafish embryos, a gradient in Nodal signalling orchestrates pattern-preserving internalization movements by triggering a motility-driven unjamming transition. In addition to its role as a morphogen determining embryo patterning, graded Nodal signalling mechanically subdivides the mesendoderm into a small fraction of highly protrusive leader cells, able to autonomously internalize via local unjamming, and less protrusive followers, which need to be pulled inwards by the leaders. The Nodal gradient further enforces a code of preferential adhesion coupling leaders to their immediate followers, resulting in a collective and ordered mode of internalization that preserves mesendoderm patterning. Integrating this dual mechanical role of Nodal signalling into minimal active particle simulations quantitatively predicts both physiological and experimentally perturbed internalization movements. This provides a quantitative framework for how a morphogen-encoded unjamming transition can bidirectionally couple tissue mechanics with patterning during complex three-dimensional morphogenesis.","lang":"eng"}]},{"keyword":["superconducting devices","superconducting properties and materials"],"volume":18,"status":"public","publication_identifier":{"eissn":["1745-2481"],"issn":["1745-2473"]},"type":"journal_article","month":"02","isi":1,"language":[{"iso":"eng"}],"year":"2022","page":"126","doi":"10.1038/s41567-021-01459-x","citation":{"apa":"Higginbotham, A.

We use machine learning and free-energy methods to overcome the limitations of quantum mechanical simulations and characterize hydrogen diffusion, superionic transitions and phase behaviours of water at extreme conditions. We predict that close-packed superionic phases, which have a fraction of mixed stacking for finite systems, are stable over a wide temperature and pressure range, whereas a body-centred cubic superionic phase is only thermodynamically stable in a small window but is kinetically favoured.

The recent observation of quantum anomalous Hall effects in narrow-band moiré materials4,5,6,7 has led to the theoretical prediction that such phases could be realized at zero magnetic field8,9,10,11,12.

Here we study epithelial cell monolayers on corrugated hydrogels engineered into wavy patterns, examining how concave and convex curvatures affect cellular and nuclear shape. We find that substrate curvature affects monolayer thickness, which is larger in valleys than crests. We show that this feature generically arises in a vertex model, leading to the hypothesis that cells may sense curvature by modifying the thickness of the tissue. We find that local curvature also affects nuclear morphology and positioning, which we explain by extending the vertex model to take into account membrane–nucleus interactions, encoding thickness modulation in changes to nuclear deformation and position. We propose that curvature governs the spatial distribution of yes-associated proteins via nuclear shape and density changes. We show that curvature also induces significant variations in lamins, chromatin condensation and cell proliferation rate in folded epithelial tissues. Together, this work identifies active cell mechanics and nuclear mechanoadaptation as the key players of the mechanistic regulation of epithelia to substrate curvature."}],"project":[{"call_identifier":"H2020","grant_number":"851288","name":"Design Principles of Branching Morphogenesis","_id":"05943252-7A3F-11EA-A408-12923DDC885E"},{"call_identifier":"FWF","name":"Active mechano-chemical description of the cell cytoskeleton","grant_number":"P31639","_id":"268294B6-B435-11E9-9278-68D0E5697425"}],"external_id":{"isi":["000720204300004"]},"date_created":"2021-11-28T23:01:29Z","title":"Cell monolayers sense curvature by exploiting active mechanics and nuclear mechanoadaptation","author":[{"last_name":"Luciano","first_name":"Marine","full_name":"Luciano, Marine"},{"id":"31D2C804-F248-11E8-B48F-1D18A9856A87","full_name":"Xue, Shi-lei","first_name":"Shi-lei","last_name":"Xue"},{"full_name":"De Vos, Winnok H.","first_name":"Winnok H.","last_name":"De Vos"},{"last_name":"Redondo-Morata","first_name":"Lorena","full_name":"Redondo-Morata, Lorena"},{"full_name":"Surin, Mathieu","first_name":"Mathieu","last_name":"Surin"},{"full_name":"Lafont, Frank","last_name":"Lafont","first_name":"Frank"},{"orcid":"0000-0001-6005-1561","first_name":"Edouard B","last_name":"Hannezo","id":"3A9DB764-F248-11E8-B48F-1D18A9856A87","full_name":"Hannezo, Edouard B"},{"full_name":"Gabriele, Sylvain","first_name":"Sylvain","last_name":"Gabriele"}],"type":"journal_article","acknowledgement":"S.G. acknowledges funding from FEDER Prostem Research Project no. 1510614 (Wallonia DG06), F.R.S.-FNRS Epiforce Research Project no.

In the context of the Kitaev model, finite magnetic fields introduce interactions between the elementary excitations, and thus the effects of high magnetic fields that are comparable to the spin-exchange energy scale must be explored. Here, we report measurements of the magnetotropic coefficient—the thermodynamic coefficient associated with magnetic anisotropy—over a wide range of magnetic fields and temperatures. We find that magnetic field and temperature compete to determine the magnetic response in a way that is independent of the large intrinsic exchange-interaction energy.

However, how mechanical and chemical signalling are integrated at the cellular level to give rise to such collective behaviours remains unclear. We address this by focusing on the highly conserved phenomenon of spatiotemporal waves of density and extracellular signal-regulated kinase (ERK) activation, which appear both in vitro and in vivo during collective cell migration and wound healing. First, we propose a biophysical theory, backed by mechanical and optogenetic perturbation experiments, showing that patterns can be quantitatively explained by a mechanochemical coupling between active cellular tensions and the mechanosensitive ERK pathway. Next, we demonstrate how this biophysical mechanism can robustly induce long-ranged order and migration in a desired orientation, and we determine the theoretically optimal wavelength and period for inducing maximal migration towards free edges, which fits well with experimentally observed dynamics. We thereby provide a bridge between the biophysical origin of spatiotemporal instabilities and the design principles of robust and efficient long-ranged migration.","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","publication":"Nature Physics","date_published":"2021-02-01T00:00:00Z","corr_author":"1","volume":17,"publication_identifier":{"issn":["1745-2473"],"eissn":["1745-2481"]},"status":"public","ec_funded":1,"acknowledgement":"We would like to thank G.

Ionization-delay measurements in atomic targets provide a wealth of information about the timing of the photoelectric effect, resonances, electron correlations and transport. However, extending this approach to molecules presents challenges, such as identifying the correct ionization channels and the effect of the anisotropic molecular landscape on the measured delays. Here, we measure ionization delays from ethyl iodide around a giant dipole resonance. By using the theoretical value for the iodine atom as a reference, we disentangle the contribution from the functional ethyl group, which is responsible for the characteristic chemical reactivity of a molecule. We find a substantial additional delay caused by the presence of a functional group, which encodes the effect of the molecular potential on the departing electron. Such information is inaccessible to the conventional approach of measuring photoionization cross-sections.

The majority of high-temperature experiments performed thus far, however, have been unable to discern whether the antinodal states are rendered unobservable due to their damping or whether they vanish due to their gapping7,8,9,10,11,12,13,14,15,16,17,18. Here, we distinguish between these two scenarios by using quantum oscillations to examine whether the small Fermi surface pocket, found to occupy only 2% of the Brillouin zone in the underdoped cuprates19,20,21,22,23,24, exists in isolation against a majority of completely gapped density of states spanning the antinodes, or whether it is thermodynamically coupled to a background of ungapped antinodal states. We find that quantum oscillations associated with the small Fermi surface pocket exhibit a signature sawtooth waveform characteristic of an isolated two-dimensional Fermi surface pocket25,26,27,28,29,30,31,32. This finding reveals that the antinodal states are destroyed by a hard gap that extends over the majority of the Brillouin zone, placing strong constraints on a drastic underlying origin of quasiparticle disappearance over almost the entire Brillouin zone in the pseudogap regime7,8,9,10,11,12,13,14,15,16,17,18.","lang":"eng"}],"date_updated":"2025-07-10T11:54:52Z","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2005.14123"}]},{"language":[{"iso":"eng"}],"publication":"Nature Physics","user_id":"D865714E-FA4E-11E9-B85B-F5C5E5697425","year":"2020","extern":"1","publication_status":"published","issue":"1","doi":"10.1038/s41567-019-0677-3","page":"63–68","date_published":"2020-01-01T00:00:00Z","date_created":"2019-10-31T07:51:44Z","title":"Jigsaw puzzle design of pluripotent origami","author":[{"full_name":"Dieleman, Peter","first_name":"Peter","last_name":"Dieleman"},{"last_name":"Vasmel","first_name":"Niek","full_name":"Vasmel, Niek"},{"orcid":"0000-0002-2299-3176","last_name":"Waitukaitis","first_name":"Scott R","full_name":"Waitukaitis, Scott R","id":"3A1FFC16-F248-11E8-B48F-1D18A9856A87"},{"full_name":"van Hecke, Martin","last_name":"van Hecke","first_name":"Martin"}],"month":"01","abstract":[{"text":"Origami is rapidly transforming the design of robots1,2, deployable structures3,4,5,6 and metamaterials7,8,9,10,11,12,13,14. However, as foldability requires a large number of complex compatibility conditions that are difficult to satisfy, the design of crease patterns is limited to heuristics and computer optimization. Here we introduce a systematic strategy that enables intuitive and effective design of complex crease patterns that are guaranteed to fold. First, we exploit symmetries to construct 140 distinct foldable motifs, and represent these as jigsaw puzzle pieces. We then show that when these pieces are fitted together they encode foldable crease patterns. This maps origami design to solving combinatorial problems, which allows us to systematically create, count and classify a vast number of crease patterns. We show that all of these crease patterns are pluripotent—capable of folding into multiple shapes—and solve exactly for the number of possible shapes for each pattern. Finally, we employ our framework to rationally design a crease pattern that folds into two independently defined target shapes, and fabricate such pluripotent origami. Our results provide physicists, mathematicians and engineers with a powerful new design strategy.","lang":"eng"}],"date_updated":"2021-01-12T08:11:16Z","intvolume":"        16","article_type":"letter_note","_id":"6976","type":"journal_article","oa_version":"None","article_processing_charge":"No","day":"01","volume":16,"citation":{"apa":"Dieleman, P., Vasmel, N., Waitukaitis, S.

For twist angles near θ ≈ 1.1°, the low-energy electronic structure of twisted bilayer graphene features isolated bands with a flat dispersion1,2. Recent experiments have observed a variety of low-temperature phases that appear to be driven by electron interactions, including insulating states, superconductivity and magnetism3,4,5,6. Here we report electrical transport measurements up to room temperature for twist angles varying between 0.75° and 2°. We find that the resistivity, ρ, scales linearly with temperature, T, over a wide range of T before falling again owing to interband activation. The T-linear response is much larger than observed in monolayer graphene for all measured devices, and in particular increases by more than three orders of magnitude in the range where the flat band exists. Our results point to the dominant role of electron–phonon scattering in twisted bilayer graphene, with possible implications for the origin of the observed superconductivity.","lang":"eng"}],"external_id":{"arxiv":["1902.00763"]},"date_created":"2022-01-13T15:00:58Z","author":[{"id":"edfc7cb1-526e-11ec-b05a-e6ecc27e4e48","full_name":"Polshyn, Hryhoriy","orcid":"0000-0001-8223-8896","first_name":"Hryhoriy","last_name":"Polshyn"},{"full_name":"Yankowitz, Matthew","last_name":"Yankowitz","first_name":"Matthew"},{"last_name":"Chen","first_name":"Shaowen","full_name":"Chen, Shaowen"},{"full_name":"Zhang, Yuxuan","last_name":"Zhang","first_name":"Yuxuan"},{"full_name":"Watanabe, K.","first_name":"K.","last_name":"Watanabe"},{"full_name":"Taniguchi, T.","last_name":"Taniguchi","first_name":"T."},{"full_name":"Dean, Cory R.","last_name":"Dean","first_name":"Cory R."},{"last_name":"Young","first_name":"Andrea F.","full_name":"Young, Andrea F."}],"title":"Large linear-in-temperature resistivity in twisted bilayer graphene","day":"05","_id":"10621","oa_version":"Preprint","article_processing_charge":"No","scopus_import":"1","article_type":"original","intvolume":"        15","publisher":"Springer Nature","citation":{"ama":"Polshyn H, Yankowitz M, Chen S, et al.

At equilibrium, the structure is encoded through specific interactions2,3,4,5,6,7,8, at an unfavourable entropic cost for the system. An alternative approach, widely used by nature, uses energy input to bypass the entropy bottleneck and develop features otherwise impossible at equilibrium9. Dissipative building blocks that inject energy locally were made available by recent advances in colloidal science10,11 but have not been used to control self-assembly. Here we show the targeted formation of self-powered microgears from active particles and their autonomous synchronization into dynamical superstructures. We use a photoactive component that consumes fuel, haematite, to devise phototactic microswimmers that form self-spinning microgears following spatiotemporal light patterns. The gears are coupled via their chemical clouds by diffusiophoresis12 and constitute the elementary bricks of synchronized superstructures, which autonomously regulate their dynamics. The results are quantitatively rationalized on the basis of a stochastic description of diffusio-phoretic oscillators dynamically coupled by chemical gradients. Our findings harness non-equilibrium phoretic phenomena to program interactions and direct self-assembly with fidelity and specificity. It lays the groundwork for the autonomous construction of dynamical architectures and functional micro-machinery.","lang":"eng"}],"main_file_link":[{"url":"https://arxiv.org/abs/1810.01033","open_access":"1"}],"date_updated":"2023-02-23T13:48:02Z","title":"Targeted assembly and synchronization of self-spinning microgears","author":[{"full_name":"Aubret, Antoine","first_name":"Antoine","last_name":"Aubret"},{"last_name":"Youssef","first_name":"Mena","full_name":"Youssef, Mena"},{"last_name":"Sacanna","first_name":"Stefano","full_name":"Sacanna, Stefano"},{"last_name":"Palacci","first_name":"Jérémie A","orcid":"0000-0002-7253-9465","full_name":"Palacci, Jérémie A","id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d"}],"date_created":"2021-02-02T13:52:49Z","external_id":{"arxiv":["1810.01033"]},"date_published":"2018-11-01T00:00:00Z","publication":"Nature Physics","publication_status":"published","user_id":"D865714E-FA4E-11E9-B85B-F5C5E5697425","publisher":"Springer Nature","quality_controlled":"1","citation":{"ista":"Aubret A, Youssef M, Sacanna S, Palacci JA. 2018.

The feed-forward protocol harnesses our discovery that noise emitted from the two converter output ports is strongly correlated because both outputs record thermal motion of the same mechanical mode.

However, the amount of radiation that can ultimately be extracted from free electrons near an arbitrary material structure has remained elusive. Here we derive a fundamental upper limit to the spontaneous photon emission and energy loss of free electrons, regardless of geometry, which illuminates the effects of material properties and electron velocities. We obtain experimental evidence for our theory with quantitative measurements of Smith–Purcell radiation. Our framework allows us to make two predictions. One is a new regime of radiation operation—at subwavelength separations, slower (non-relativistic) electrons can achieve stronger radiation than fast (relativistic) electrons. The other is a divergence of the emission probability in the limit of lossless materials. We further reveal that such divergences can be approached by coupling free electrons to photonic bound states in the continuum11,12,13. Our findings suggest that compact and efficient free-electron radiation sources from microwaves to the soft X-ray regime may be achievable without requiring ultrahigh accelerating voltages.","lang":"eng"}],"date_updated":"2026-04-15T12:22:56Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.1901.06593"}],"external_id":{"arxiv":["1901.06593"]},"date_created":"2026-03-30T12:22:47Z","title":"Maximal spontaneous photon emission and energy loss from free electrons","author":[{"full_name":"Yang, Yi","last_name":"Yang","first_name":"Yi"},{"full_name":"Massuda, Aviram","last_name":"Massuda","first_name":"Aviram"},{"full_name":"Roques-Carmes, Charles","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","first_name":"Charles","last_name":"Roques-Carmes"},{"full_name":"Kooi, Steven E.","last_name":"Kooi","first_name":"Steven E."},{"full_name":"Christensen, Thomas","last_name":"Christensen","first_name":"Thomas"},{"first_name":"Steven G.","last_name":"Johnson","full_name":"Johnson, Steven G."},{"full_name":"Joannopoulos, John D.","last_name":"Joannopoulos","first_name":"John D."},{"full_name":"Miller, Owen D.","last_name":"Miller","first_name":"Owen D."},{"full_name":"Kaminer, Ido","last_name":"Kaminer","first_name":"Ido"},{"full_name":"Soljačić, Marin","last_name":"Soljačić","first_name":"Marin"}],"OA_type":"green","date_published":"2018-09-01T00:00:00Z","publication":"Nature Physics","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","publisher":"Springer Nature","quality_controlled":"1","citation":{"chicago":"Yang, Yi, Aviram Massuda, Charles Roques-Carmes, Steven E.

However, a range of aberrant processes involve the self-replication of pathological protein structures without any additional assistance. One example is the autocatalytic generation of pathological protein aggregates, including amyloid fibrils, involved in neurodegenerative disorders. Here, we use computer simulations to identify the necessary requirements for the self-replication of fibrillar assemblies of proteins. We establish that a key physical determinant for this process is the affinity of proteins for the surfaces of fibrils. We find that self-replication can take place only in a very narrow regime of inter-protein interactions, implying a high level of sensitivity to system parameters and experimental conditions. We then compare our theoretical predictions with kinetic and biosensor measurements of fibrils formed from the Aβ peptide associated with Alzheimer’s disease. Our results show a quantitative connection between the kinetics of self-replication and the surface coverage of fibrils by monomeric proteins. These findings reveal the fundamental physical requirements for the formation of supra-molecular structures able to replicate themselves, and shed light on mechanisms in play in the proliferation of protein aggregates in nature."}]}]
