[{"title":"Quantum control of Hubbard excitons","publication":"Nature Materials","abstract":[{"lang":"eng","text":"Quantum control of the many-body wavefunction is a central challenge in quantum materials research, as it could yield a precise control knob to manipulate emergent phenomena. Floquet engineering, the coherent dressing of quantum states with periodic non-resonant optical fields, has become an important strategy for quantum control. Most applications to solid-state systems have targeted weakly interacting or single-ion states, leaving the manipulation of many-body wavefunctions largely unexplored. Here we use Floquet engineering to achieve quantum control of a strongly correlated Hubbard exciton in the one-dimensional Mott insulator Sr2CuO3. A non-resonant mid-infrared optical field coherently dresses the exciton wavefunction, driving its rotation between bright and dark states. We use resonant third-harmonic generation to quantify ultrafast π/2 rotations on the Bloch sphere spanned by these exciton states. Our work advances the quest towards programmable control of correlated states and exciton-based quantum sensing."}],"external_id":{"arxiv":["2601.20695 "]},"article_processing_charge":"No","arxiv":1,"type":"journal_article","month":"03","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Baykusheva DR, Carmichael D, Weber CS, Lu IT, Glerean F, Meng T, De Oliveira PBM, Homes CC, Zaliznyak IA, Gu GD, Dean MPM, Rubio A, Kennes DM, Claassen M, Mitrano M. 2026.

Unlike normal (slip) bonds, catch bonds strengthen under tension. The current paradigm is that this feature provides ‘strength on demand3’, thus enabling cells to increase rigidity under stress1,4,5,6. However, catch bonds are often weaker than slip bonds because they have cryptic binding sites that are usually buried7,8. Here we show that catch bonds render reconstituted cytoskeletal actin networks stronger than slip bonds, even though the individual bonds are weaker. Simulations show that slip bonds remain trapped in stress-free areas, whereas weak binding allows catch bonds to mitigate crack initiation by moving to high-tension areas. This ‘dissociation on demand’ explains how cells combine mechanical strength with the adaptability required for shape change, and is relevant to diseases where catch bonding is compromised7,9, including focal segmental glomerulosclerosis10 caused by the α-actinin-4 mutant studied here. We surmise that catch bonds are the key to create life-like materials."}],"publication":"Nature Materials","title":"Weak catch bonds make strong networks","quality_controlled":"1","language":[{"iso":"eng"}],"issue":"9","oa_version":"Preprint","oa":1,"department":[{"_id":"MiSi"}],"acknowledgement":"We thank M. van Hecke and C.

Group IV hole spin qubits have moved into the focus of interest due to the ease of operation and compatibility with Si technology. In addition, Ge offers the option for monolithic superconductor-semiconductor integration. Here we demonstrate a hole spin qubit operating at fields below 10 mT, the critical field of Al, by exploiting the large out-of-plane hole g-factors in planar Ge and by encoding the qubit into the singlet-triplet states of a double quantum dot. We observe electrically controlled X and Z-rotations with tunable frequencies exceeding 100 MHz and dephasing times of 1μs which we extend beyond 15μs with echo techniques. These results show that Ge hole singlet triplet qubits outperform their electronic Si and GaAs based counterparts in speed and coherence, respectively. In addition, they are on par with Ge single spin qubits, but can be operated at much lower fields underlining their potential for on chip integration with superconducting technologies.","lang":"eng"}],"title":"A singlet triplet hole spin qubit in planar Ge","year":"2021","day":"01","publication_status":"published","pmid":1,"status":"public","date_updated":"2026-06-27T22:30:43Z","article_type":"original","publisher":"Springer Nature","intvolume":"        20","isi":1,"corr_author":"1","date_published":"2021-08-01T00:00:00Z","author":[{"last_name":"Jirovec","first_name":"Daniel","id":"4C473F58-F248-11E8-B48F-1D18A9856A87","full_name":"Jirovec, Daniel","orcid":"0000-0002-7197-4801"},{"first_name":"Andrea C","last_name":"Hofmann","full_name":"Hofmann, Andrea C","id":"340F461A-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Ballabio, Andrea","last_name":"Ballabio","first_name":"Andrea"},{"first_name":"Philipp M.","last_name":"Mutter","full_name":"Mutter, Philipp M."},{"first_name":"Giulio","last_name":"Tavani","full_name":"Tavani, Giulio"},{"last_name":"Botifoll","first_name":"Marc","full_name":"Botifoll, Marc"},{"full_name":"Crippa, Alessandro","id":"1F2B21A2-F6E7-11E9-9B82-F7DBE5697425","orcid":"0000-0002-2968-611X","first_name":"Alessandro","last_name":"Crippa"},{"id":"3F5D8856-F248-11E8-B48F-1D18A9856A87","full_name":"Kukucka, Josip","last_name":"Kukucka","first_name":"Josip"},{"first_name":"Oliver","last_name":"Sagi","full_name":"Sagi, Oliver","id":"71616374-A8E9-11E9-A7CA-09ECE5697425"},{"last_name":"Martins","first_name":"Frederico","orcid":"0000-0003-2668-2401","id":"38F80F9A-1CB8-11EA-BC76-B49B3DDC885E","full_name":"Martins, Frederico"},{"first_name":"Jaime","last_name":"Saez Mollejo","full_name":"Saez Mollejo, Jaime","id":"e0390f72-f6e0-11ea-865d-862393336714"},{"id":"2A307FE2-F248-11E8-B48F-1D18A9856A87","full_name":"Prieto Gonzalez, Ivan","orcid":"0000-0002-7370-5357","last_name":"Prieto Gonzalez","first_name":"Ivan"},{"first_name":"Maksim","last_name":"Borovkov","full_name":"Borovkov, Maksim","id":"2ac7a0a2-3562-11eb-9256-fbd18ea55087"},{"first_name":"Jordi","last_name":"Arbiol","full_name":"Arbiol, Jordi"},{"first_name":"Daniel","last_name":"Chrastina","full_name":"Chrastina, Daniel"},{"last_name":"Isella","first_name":"Giovanni","full_name":"Isella, Giovanni"},{"orcid":"0000-0001-8342-202X","full_name":"Katsaros, Georgios","id":"38DB5788-F248-11E8-B48F-1D18A9856A87","first_name":"Georgios","last_name":"Katsaros"}]},{"language":[{"iso":"eng"}],"quality_controlled":"1","OA_place":"repository","department":[{"_id":"NanoFab"}],"oa":1,"oa_version":"Preprint","date_created":"2020-05-03T22:00:49Z","doi":"10.1038/s41563-020-0665-0","_id":"7792","publication_identifier":{"eissn":["1476-4660"],"issn":["1476-1122"]},"acknowledgement":"J.T.-G. and G.Á.-P. acknowledge support through the Severo Ochoa Program from the Government of the Principality of Asturias (nos.

However, the lack of tunability of their narrow and material-specific spectral range—the Reststrahlen band—severely limits their technological implementation. Here, we demonstrate that intercalation of Na atoms in the van der Waals semiconductor α-V2O5 enables a broad spectral shift of Reststrahlen bands, and that the phonon polaritons excited show ultra-low losses (lifetime of 4 ± 1 ps), similar to phonon polaritons in a non-intercalated crystal (lifetime of 6 ± 1 ps).

Their disparate ground states largely depend on transition metal d-electron-derived electronic states, on which the vast majority of attention has been concentrated to date. Here, we focus on the chalcogen-derived states. From density-functional theory calculations together with spin- and angle-resolved photoemission, we find that these generically host a co-existence of type-I and type-II three-dimensional bulk Dirac fermions as well as ladders of topological surface states and surface resonances. We demonstrate how these naturally arise within a single p-orbital manifold as a general consequence of a trigonal crystal field, and as such can be expected across a large number of compounds. Already, we demonstrate their existence in six separate TMDs, opening routes to tune, and ultimately exploit, their topological physics."}],"volume":17,"article_processing_charge":"No","page":"21-28","external_id":{"arxiv":["1702.08177"],"pmid":["29180775"]},"arxiv":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"01","type":"journal_article","scopus_import":"1","citation":{"ista":"Bahramy MS, Clark OJ, Yang B-J, Feng J, Bawden L, Riley JM, Marković I, Mazzola F, Sunko V, Biswas D, Cooil SP, Jorge M, Wells JW, Leandersson M, Balasubramanian T, Fujii J, Vobornik I, Rault JE, Kim TK, Hoesch M, Okawa K, Asakawa M, Sasagawa T, Eknapakul T, Meevasana W, King PDC. 2018.

Here, using a quantum gas to engineer an adjustable interaction at the microscopic level, we demonstrate scenarios of competition, coexistence and mutual enhancement of two orders. For the enhancement scenario, the presence of one order lowers the critical point of the other. Our system is realized by a Bose–Einstein condensate that can undergo self-organization phase transitions in two optical resonators17, resulting in two distinct crystalline density orders. We characterize the coupling between these orders by measuring the composite order parameter and the elementary excitations and explain our results with a mean-field free-energy model derived from a microscopic Hamiltonian.

Here, we demonstrate robust assembly of DNA origami filaments into cholesteric liquid crystals, one-dimensional supramolecular twisted ribbons and two-dimensional colloidal membranes. The exquisite control afforded by the DNA origami technology establishes a quantitative relationship between the microscopic filament structure and the macroscopic cholesteric pitch. Furthermore, it also enables robust assembly of one-dimensional twisted ribbons, which behave as effective supramolecular polymers whose structure and elastic properties can be precisely tuned by controlling the geometry of the elemental building blocks. Our results demonstrate the potential synergy between DNA origami technology and colloidal science, in which the former allows for rapid and robust synthesis of complex particles, and the latter can be used to assemble such particles into bulk materials.","lang":"eng"}],"publication":"Nature Materials","external_id":{"arxiv":["1705.08944"],"pmid":["28530665"]},"article_processing_charge":"No","page":"849-856","arxiv":1,"date_updated":"2023-11-07T11:40:00Z","publisher":"Springer Nature","article_type":"original","pmid":1,"publication_status":"published","status":"public","year":"2017","day":"22","author":[{"full_name":"Siavashpouri, M","last_name":"Siavashpouri","first_name":"M"},{"full_name":"Wachauf, CH","last_name":"Wachauf","first_name":"CH"},{"first_name":"MJ","last_name":"Zakhary","full_name":"Zakhary, MJ"},{"id":"dfec9381-4341-11ee-8fd8-faa02bba7d62","full_name":"Praetorius, Florian M","last_name":"Praetorius","first_name":"Florian M"},{"last_name":"Dietz","first_name":"H","full_name":"Dietz, H"},{"first_name":"Z","last_name":"Dogic","full_name":"Dogic, Z"}],"date_published":"2017-05-22T00:00:00Z","intvolume":"        16","extern":"1"},{"article_type":"original","publisher":"Springer Nature","date_updated":"2021-01-12T08:12:43Z","publication_status":"published","status":"public","day":"28","year":"2016","author":[{"last_name":"Mourad","first_name":"Eléonore","full_name":"Mourad, Eléonore"},{"first_name":"Laura","last_name":"Coustan","full_name":"Coustan, Laura"},{"first_name":"Pierre","last_name":"Lannelongue","full_name":"Lannelongue, Pierre"},{"full_name":"Zigah, Dodzi","first_name":"Dodzi","last_name":"Zigah"},{"first_name":"Ahmad","last_name":"Mehdi","full_name":"Mehdi, Ahmad"},{"full_name":"Vioux, André","last_name":"Vioux","first_name":"André"},{"orcid":"0000-0003-2902-5319","full_name":"Freunberger, Stefan Alexander","id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425","first_name":"Stefan Alexander","last_name":"Freunberger"},{"last_name":"Favier","first_name":"Frédéric","full_name":"Favier, Frédéric"},{"full_name":"Fontaine, Olivier","last_name":"Fontaine","first_name":"Olivier"}],"date_published":"2016-11-28T00:00:00Z","extern":"1","intvolume":"        16","citation":{"ista":"Mourad E, Coustan L, Lannelongue P, Zigah D, Mehdi A, Vioux A, Freunberger SA, Favier F, Fontaine O. 2016.

Yet, the solid state maximizes the density of redox species, which is at least two orders of magnitude lower in liquids because of solubility limitations. With regard to electrochemical energy storage devices, this leads to high-energy batteries with limited power and high-power supercapacitors with a well-known energy deficiency. For such devices the ideal system should endow the liquid state with a density of redox species close to the solid state. Here we report an approach based on biredox ionic liquids to achieve bulk-like redox density at liquid-like fast kinetics. The cation and anion of these biredox ionic liquids bear moieties that undergo very fast reversible redox reactions. As a first demonstration of their potential for high-capacity/high-rate charge storage, we used them in redox supercapacitors. These ionic liquids are able to decouple charge storage from an ion-accessible electrode surface, by storing significant charge in the pores of the electrodes, to minimize self-discharge and leakage current as a result of retaining the redox species in the pores, and to raise working voltage due to their wide electrochemical window.","lang":"eng"}],"publication":"Nature Materials","page":"446-453","article_processing_charge":"No","external_id":{"arxiv":["1711.11518"]},"arxiv":1},{"title":"A stable cathode for the aprotic Li–O2 battery","author":[{"first_name":"Muhammed M.","last_name":"Ottakam Thotiyl","full_name":"Ottakam Thotiyl, Muhammed M."},{"id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425","full_name":"Freunberger, Stefan Alexander","orcid":"0000-0003-2902-5319","last_name":"Freunberger","first_name":"Stefan Alexander"},{"last_name":"Peng","first_name":"Zhangquan","full_name":"Peng, Zhangquan"},{"first_name":"Yuhui","last_name":"Chen","full_name":"Chen, Yuhui"},{"last_name":"Liu","first_name":"Zheng","full_name":"Liu, Zheng"},{"full_name":"Bruce, Peter G.","first_name":"Peter G.","last_name":"Bruce"}],"volume":12,"publication":"Nature Materials","abstract":[{"lang":"eng","text":"Rechargeable lithium–air (O2) batteries are receiving intense interest because their high theoretical specific energy exceeds that of lithium-ion batteries. If the Li–O2 battery is ever to succeed, highly reversible formation/decomposition of Li2O2 must take place at the cathode on cycling. However, carbon, used ubiquitously as the basis of the cathode, decomposes during Li2O2 oxidation on charge and actively promotes electrolyte decomposition on cycling. Replacing carbon with a nanoporous gold cathode, when in contact with a dimethyl sulphoxide-based electrolyte, does seem to demonstrate better stability. However, nanoporous gold is not a suitable cathode; its high mass destroys the key advantage of Li–O2 over Li ion (specific energy), it is too expensive and too difficult to fabricate. Identifying a suitable cathode material for the Li–O2 cell is one of the greatest challenges at present. Here we show that a TiC-based cathode reduces greatly side reactions (arising from the electrolyte and electrode degradation) compared with carbon and exhibits better reversible formation/decomposition of Li2O2 even than nanoporous gold (>98% capacity retention after 100 cycles, compared with 95% for nanoporous gold); it is also four times lighter, of lower cost and easier to fabricate. The stability may originate from the presence of TiO2 (along with some TiOC) on the surface of TiC. In contrast to carbon or nanoporous gold, TiC seems to represent a more viable, stable, cathode for aprotic Li–O2 cells."}],"date_published":"2013-09-01T00:00:00Z","article_processing_charge":"No","page":"1050-1056","intvolume":"        12","extern":"1","type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2021-01-12T08:12:55Z","month":"09","article_type":"original","publisher":"Springer Nature","citation":{"ista":"Ottakam Thotiyl MM, Freunberger SA, Peng Z, Chen Y, Liu Z, Bruce PG. 2013.

Here, we describe an experimental method based on reaction–diffusion phenomena that allows for simultaneous micropatterning of a substrate with several coloured chemicals. In this method, called wet stamping (WETS), aqueous solutions of two or more inorganic salts are delivered onto a film of dry, ionically doped gelatin from an agarose stamp patterned in bas relief. Once in conformal contact, these salts diffuse into the gelatin, where they react to give deeply coloured precipitates. Separation of colours in the plane of the surface is the consequence of the differences in the diffusion coefficients, the solubility products, and the amounts of different salts delivered from the stamp, and is faithfully reproduced by a theoretical model based on a system of reaction–diffusion partial differential equations. The multicolour micropatterns are useful as non-binary optical elements, and could potentially form the basis of new applications in microseparations and in controlled delivery.","lang":"eng"}],"title":"Multicolour micropatterning of thin films of dry gels","page":"729-735","external_id":{"pmid":["15378052"]},"article_processing_charge":"No"}]
