  • Previous work has suggested that at very low temperatures TbInO3 hosts an unconventional quantum ground state. Terahertz time-domain spectroscopy measurements of its excitations show that related exotic effects can persist to room temperature.

  • Much recent work has focused on the kagome metals AV3Sb5 (A = K, Rb, and Cs), but studies of the monolayer form are only just beginning. Here, the authors theoretically study monolayer kagome metals, and predict modified van Hove singularities that lead to charge-density-wave doublets and d-wave superconductivity.

  • Non-Abelian phase of Kitaev quantum spin liquid is promising for topological quantum computation. Here, the authors propose a way to identify the non-abelian Kitaev quantum spin liquid by magnetic field angle dependence, providing criteria for such a state for future experiments.

  • Combinatorial optimization is one of the areas for which quantum computing promises to overcome classical devices. An experiment with arrays of Rydberg atoms now shows how to solve combinatorial graph problems with auxiliary atomic wires.

  • Quantum magnets are a promising platform to aid in the search for a Bose-Einstein condensate and investigations into the underlying mechanisms of these materials are an active area of research. Here, the authors present a numerical study of the two-dimensional Kondo necklace model and consider the various phases which can occur under an applied magnetic field suggesting field-induced condensate phases may exist for the quantum magnet Ba2NiO2(AgSe)2.
