    The bulk photovoltaic effect holds promise for various optoelectronic applications, but it is usually restricted to non-centrosymmetric materials operating in the visible range. Here, the authors report a surface photogalvanic effect spanning from visible to midinfrared wavelengths in a centrosymmetric topological insulator, Ag2Te.

    Living cell collectives can jam and unjam through many pathways, yet the details remain elusive. Arora et al. design a monolayer of deformable cell-mimics composed of chiral active granular ellipsoids confined in flexible paper rings and show a re-entrant jamming transition mediated solely by cell shape change.

    The authors demonstrate a novel regime of coherent harmonic modulation yielding resonances (termed acceleration beats) with energy spacing and temporal correlations controlled by the modulation amplitude. These features are associated with accelerated energy-change rates during the harmonic cycle.

    Nickelates have been shown to host unconventional superconductivity, and recently it has been found that the choice of substrate can significantly change the superconducting critical temperature. This suggests, that like some Cuprates, strain could be important. Here Gao, Fan, Wang, and coauthors find that magnetic excitations in a parent Nickelate are insensitive to substrate choice, and therefore strain, which differs markedly from the case of Cuprates.

    Recent debate challenges the previous understanding of dissipative quantum phase transitions in Josephson junctions linked to resistive environments. This study reexamines the issue with a junction connected to a multimode transmission line, using exact diagonalization to show the transition's emergence with increased system size and clarifying the universal spectrum at the critical point.

    Particles at fluid interfaces aggregate due to capillary attraction, but introducing magnets creates a competing repulsion effect, influencing pattern formation. Authors report how short-range attraction and long-range repulsion interactions govern the transition from repulsive lattices to clustered and striped patterns as particle density increases.

    Most rod-shaped bacteria elongate using a protein complex, the elongasome, that inserts new cell wall material into the cell sidewall. Here, Middlemiss et al. track the movement of individual elongasomes around the circumference of Bacillus subtilis cells, providing evidence for a molecular motor tug-of-war competition between oppositely oriented cell-wall synthesis complexes.

    Kagome materials host nearly dispersionless electronic bands, but an ideal flat band close to the Fermi level is difficult to realize. Here the authors report evidence for a flat band near the Fermi level and flat-band-originated ferromagnetic fluctuation induced by orbital selective correlations in Sc3Mn3Al7Si5.

    The Mermin-Wagner theorem states that for short-range isotropic interactions, magnetic order in two dimensions is destroyed by magnetic fluctuations at finite temperatures. Observing this situation is challenging due to the finite size of typical laboratory samples. Here, Kiaba et al observe the suppression of magnetic order in oxide superlattices, at the thickness of the superlattice layers are reduced to one monolayer.

    Flat electronic bands can give rise to correlation-driven phases but for this, they need to be tuned to the Fermi level. Here the authors predict flat bands pinned at the Fermi level due to orbital-selective interactions and discuss implications for the design of topological Kondo semimetal in d-electron systems.

    The recently-developed topological heavy fermion model explains the low energy electrons of magic-angle twisted bilayer graphene as a hybridization between states localized at AA stacking sites and itinerant topological states, denoted by f and c electrons in analogy to heavy fermion systems. Here, the authors extend this model to a nonzero magnetic field, obtaining interacting Hofstadter spectra in the flatband limit by analytic methods.

    Quantum kernel methods are usually believed to enjoy better trainability than quantum neural networks which may suffer from a well-studied barren plateau. Here, building over previous evidence, the authors show that practical implications of exponential concentration result in a trivial data-insensitive model after training, and identify commonly used features that induce the concentration.
