    Josephson junction arrays lead quantum circuitry research, vital for quantum computing, simulation, and metrology. Here the authors show that increasing the number of links in an atomtronic Josephson junction necklace enhances the atomic circuit’s resilience to higher circulations, corresponding to higher critical currents.

    Metastable states found in superconductors and charge density wave materials are of fundamental interest. Vodeb et al. study the domain wall dynamics in 1T-TaS2 using scanning tunneling microscopy and a quantum annealer, finding that in both cases the dynamics is driven by spectrally similar noise.

    Network memory impacts dynamical processes emerging in real-world social systems, however little is known about memory of temporal networks beyond pairwise interactions. The authors develop a framework to characterize the temporal organization of higher-order networks and propose a model of temporal hypergraphs with higher-order memory to reproduce the patterns emerging in real-world complex systems.

    Liquid-solid contact electrification is widely used in various applications, yet its mechanism remains not well understood. Jin et al. show that the effect arises from electron transfer due to the work function difference between liquids and superhydrophobic surfaces and rule out the possibility of ion transfer.

    Perturbing a physical system, for example, picking a guitar string to make it vibrate, tells a lot about its intrinsic properties. Here the authors show that such concepts hold even for quantum gases of light, which respond to a perturbation with the same dynamics as they fluctuate on their own.

    CrSBr is a van der Waals layered antiferromagnet. Unlike many other van der Waals magnetic materials it is air stable, and in addition hosts a rich array of magneto-optical responses. Here, Tabataba-Vakili et al demonstrate that the magnetic and optical response of CrSBr is sensitive to gating, allowing electrical control of the magneto-optical properties.

    This study explores alternative stable states in microbial communities. Focusing on a respiratory tract community of 6 species, the authors identified four distinct stable states that are predicted to be driven by cooperative growth. The findings contrast with the common association between competitive interactions and multistability in microbial communities.

    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.

    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.
