text: Strongly correlated systems can exhibit unexpected phenomena when brought
in a state far from equilibrium. An example is many-body localization, which prevents
generic interacting systems from reaching thermal equilibrium even at long times1,2.
The stability of the many-body localized phase has been predicted to be hindered
by the presence of small thermal inclusions that act as a bath, leading to the
delocalization of the entire system through an avalanche propagation mechanism3,4,5,6,7,8.
Here we study the dynamics of a thermal inclusion of variable size when it is
coupled to a many-body localized system. We find evidence for accelerated transport
of thermal inclusion into the localized region. We monitor how the avalanche spreads
through the localized system and thermalizes it site by site by measuring the
site-resolved entropy over time. Furthermore, we isolate the strongly correlated
bath-induced dynamics with multipoint correlations between the bath and the system.
Our results have implications on the robustness of many-body localized systems
and their critical behaviour.

text: As developing tissues grow in size and undergo morphogenetic changes, their
material properties may be altered. 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.

text: Arrays of Josephson junctions are governed by a competition between superconductivity
and repulsive Coulomb interactions, and are expected to exhibit diverging low-temperature
resistance when interactions exceed a critical level. 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.

text: Embryo development requires biochemical signalling to generate patterns of
cell fates and active mechanical forces to drive tissue shape changes. 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.

which can hamper their performance. It is widely believed that external radiation
is responsible but a study now suggests there must be an additional, unknown source.

text: Most water in the Universe may be superionic, and its thermodynamic and transport
properties are crucial for planetary science but difficult to probe experimentally
or theoretically. 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. Our phase boundaries, which are consistent
with existing—albeit scarce—experimental observations, help resolve the fractions
of insulating ice, different superionic phases and liquid water inside ice giants.

text: The early development of many organisms involves the folding of cell monolayers,
but this behaviour is difficult to reproduce in vitro; therefore, both mechanistic
causes and effects of local curvature remain unclear. 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.

text: When a flat band is partially filled with electrons, strong Coulomb interactions
between them may lead to the emergence of topological gapped states with quantized
Hall conductivity. Such emergent topological states have been found in partially
filled Landau levels1 and Hofstadter bands2,3; however, in both cases, a large
magnetic field is required to produce the underlying flat band. 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 report the observation of insulators with Chern number
C = 1 in the zero-magnetic-field limit at half-integer filling of the moiré superlattice
unit cell in twisted monolayer–bilayer graphene7,13,14,15. Chern insulators in
a half-filled band suggest the spontaneous doubling of the superlattice unit cell2,3,16,
and our calculations find a ground state of the topological charge density wave
at half-filling of the underlying band. The discovery of these topological phases
at fractional superlattice filling enables the further pursuit of zero-magnetic-field
phases that have fractional statistics that exist either as elementary excitations
or bound to lattice dislocations.

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.
This emergent scale-invariant magnetic anisotropy provides evidence for a high
degree of exchange frustration that favours the formation of a spin liquid state
in RuCl3.

text: Collective cell migration offers a rich field of study for non-equilibrium
physics and cellular biology, revealing phenomena such as glassy dynamics, pattern
formation and active turbulence. 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.

text: Thermalization is the inevitable fate of many complex quantum systems, whose
dynamics allow them to fully explore the vast configuration space regardless of
the initial state---the behaviour known as quantum ergodicity. In a quest for
experimental realizations of coherent long-time dynamics, efforts have focused
on ergodicity-breaking mechanisms, such as integrability and localization. The
recent discovery of persistent revivals in quantum simulators based on Rydberg
atoms have pointed to the existence of a new type of behaviour where the system
rapidly relaxes for most initial conditions, while certain initial states give
rise to non-ergodic dynamics. This collective effect has been named ”quantum many-body
scarring’by analogy with a related form of weak ergodicity breaking that occurs
for a single particle inside a stadium billiard potential. In this Review, we
provide a pedagogical introduction to quantum many-body scars and highlight the
emerging connections with the semiclassical quantization of many-body systems.
We discuss the relation between scars and more general routes towards weak violations
of ergodicity due to embedded algebras and non-thermal eigenstates, and highlight
possible applications of scars in quantum technology.

text: Attosecond chronoscopy has revealed small but measurable delays in photoionization,
characterized by the ejection of an electron on absorption of a single photon.
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 results establish ionization-delay measurements
as a valuable tool in investigating the electronic properties of molecules.

text: Partially filled Landau levels host competing electronic orders. For example,
electron solids may prevail close to integer filling of the Landau levels before
giving way to fractional quantum Hall liquids at higher carrier density1,2. Here,
we report the observation of an electron solid with non-collinear spin texture
in monolayer graphene, consistent with solidification of skyrmions3—topological
spin textures characterized by quantized electrical charge4,5. We probe the spin
texture of the solids using a modified Corbino geometry that allows ferromagnetic
magnons to be launched and detected6,7. We find that magnon transport is highly
efficient when one Landau level is filled (ν=1), consistent with quantum Hall
ferromagnetic spin polarization. However, even minimal doping immediately quenches
the magnon signal while leaving the vanishing low-temperature charge conductivity
unchanged. Our results can be understood by the formation of a solid of charged
skyrmions near ν=1, whose non-collinear spin texture leads to rapid magnon decay.
Data near fractional fillings show evidence of several fractional skyrmion solids,
suggesting that graphene hosts a highly tunable landscape of coupled spin and
charge orders.

text: An understanding of the missing antinodal electronic excitations in the pseudogap
state is essential for uncovering the physics of the underdoped cuprate high-temperature
superconductors1,2,3,4,5,6. 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.

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.

text: Twisted bilayer graphene has recently emerged as a platform for hosting correlated
phenomena. 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.

text: Free-electron radiation such as Cerenkov1, Smith–Purcell2 and transition radiation3,4
can be greatly affected by structured optical environments, as has been demonstrated
in a variety of polaritonic5,6, photonic-crystal7 and metamaterial8,9,10 systems.
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.

text: 'Self-assembly is the autonomous organization of components into patterns
or structures: an essential ingredient of biology and a desired route to complex
organization1. 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.'

text: The ability of biological molecules to replicate themselves is the foundation
of life, requiring a complex cellular machinery. 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.
