  • Strings of local excitations are interesting features of a strongly correlated topological quantum matter. Here, the authors show that Boltzmann-distributed strings of local excitations also describe the topological physics of the Santa Fe geometry of artificial spin ice, which is a classical thermal system.

  • Artificial spin-ice materials are usually described by spins that are either up or down. Here, a new type of spin ice is fabricated where the spins can be in one of three states with different coexisting phases separated by a first-order transition.

  • The structure of a conserved hairpin loop involved in peptidyl–tRNA recognition by SOS ribosomal subunits has been solved by NMR. The loop is closed by a novel G–C base pair and presents guanine residues for RNA recognition.

  • Experiments on the Shakti geometry of artificial spin ice show that its low-energy excitations are topologically protected, and that an emergent classical topological order influences the ergodicity and equilibration of this nanomagnetic system.

  • Recently there has been interest in exploring the coupling between magnons for use in information processing, however, this is hampered by the fact that such coupling is forbidden due to the different parity of the acoustic and optical magnons. Here, Comstock et al show that the interlayer Dzyaloshinskii–Moriya-Interaction in a layered hybrid antiferromagnet can allow for strong coupling between the acoustic and optical magnons, offering a pathway for magnon coherent information processing.

  • Long-range order is normally related to an entropy decrease. Yet, an increase in entropy in one part of a system can induce long-range order in another. A new form of such entropy-driven order is now demonstrated in an artificial spin-ice system.

  • There are areas where high-energy and condensed-matter physics can successfully overlap a prominent example being topological matter and the role of supersymmetry. Here, via anisotropic magnetoresistance, the authors investigate distortions in the Fermi surface geometry of FeRh films and provide a theoretical interpretation that considers the results within the framework of a pseudogravitational fields.
