    Reconstructing the structure of a complex networked system and predicting its time evolution to understand its functions are usually two subjects that are treated separately. The authors propose a theoretical framework based on information theory, that uncovers the relation between reconstructability and predictability in networked systems.

    There are now several van der Waals magnets that have been shown to host skyrmions, however, these are typically hampered by a low Curie temperature, restricting the temperature at which the skyrmions can exist. Here, Zhang, Jiang, Jiang and coauthors find a skyrmion lattice in the van der Waals magnet Fe3 − xGaTe2 above room temperature and demonstrate the critical role of symmetry breaking in crystal lattice in the origin of these skyrmions.

    The authors study the [Nb/V/Ta] superconducting artificial superlattice, known to support a superconducting diode effect, by pulsed THz spectroscopy and simultaneous transport. They found a non-monotonic switching between the superconducting and normal state, which can be explained if the THz-driven vortex depinning determines the critical current.

    Toggle switching refers to the switching of magnetization induced by a train of ultrashort laser pulses. The high speed make such switching in extremely promising for devices, however, the underlying toggle switching mechanism in metals is due to heating, and thus has a downside of dissipation. Here, Zalewski et al demonstrate ultrafast ‘cold’ toggle switching, with a mechanism that does not rely on heating in dielectric Cobalt doped Yittrium Iron Garnet.

    Switchable structural and physical bistability in ferroelectric materials can be achieved as result of molecular orbital breaking. Here, the authors describe the photo-mediated bistability in organosilicon Schiff base ferroelectric crystals for the modulation of dielectric, second-harmonic generation, and ferroelectric polarization and showing good in vitro biocompatibility.

    The authors study tunneling junctions in rhombohedral MoS2 bilayers and correlate their performance with the local domain layout. They show that the switching behavior in sliding ferroelectrics is strongly dependent on the pre-existing domain structure.

    The strong connection between the dynamics of a physical system and its Hamiltonian’s spectrum has scarcely been applied in the non-Hermitian case. Here, the authors use a photonic quantum walk to confirm and expand previous theoretical analyses connecting self-acceleration dynamics with non-trivial point-gap topology.

    Topological flat bands offer a solid-state platform for studying the interplay between topology and electron correlations. Here, the authors demonstrate that a prototypical 3D Dirac material can host topological flat bands under magnetic fields due to polar-distortion-assisted Rashba splitting.

    The authors study the intrinsic superconducting diode effect (SDE) in a single Josephson junction consisting of a InGaAs/InAs/InGaAs quantum well as the weak link, and an Al film as the superconductor. They find a correspondence between SDE and an offset in the relationship between critical current and the difference in phase of the superconducting order parameter across the junction.

    It is known that spatially localized interactions can give rise to self-organized collective motion. Here, by studying pairwise interactions in juvenile zebrafish, authors reveal the role of reciprocal temporal coupling and find that temporal coordination considerably improves spatial responsiveness, such as reacting to changes in the direction of motion of a partner.

    Frustrated magnetic systems typically have multiple ground state configurations. While such multistability is common in amorphous materials, periodic mechanical systems have long range elastic interactions that tend to lead to a long-range ordered ground state. Herein, Sirote-Katz, Shohat et al. introduce periodic mechanical systems that have many disordered metastable states.

    In open-field-line magnetic plasma traps, the attainable cross-field voltage drops are limited by the tolerances of the solid materials of the vacuum vessel. Here, the authors demonstrate the possibility of equilibria that isolate large voltage drops to the interior of the plasma, circumventing this limit.

    Néel spin-orbit torques arise due to charge currents in some antiferromagnets, and have sparked interest as a possible pathway for achieving electrical control of antiferromagnetic order. While the driving of antiferromagnetic order by Néel spin-orbit torques is now experimentally well established, the inverse process, where magnetic excitations in an antiferromagnetic drive a charge current is not reported. Here Huang, Liao, Qiu, and coauthors observe this inverse process in an Mn2Au thin film.

    Extreme magnetoresistance is characterized by a large and non-saturating magnetoresistance. Typically, it is observed in materials with compensated bandstructures, however, here, Christensen et al demonstrate a large and non-saturating magnetoresistance in a γAl2O3/SrTiO3 heterostructure, which is related to disorder, rather than the materials bandstructure.
