Spinon excitations generate direct current via the shift current mechanism in a noncentrosymmetric 1D XXZ antiferromagnet with magnetoelectric coupling.
Interactions in the generalized SSH model produce interacting SPT phases, a sublattice-density-breaking phase, CDW phases, Luttinger liquids, and a gapless SPT phase with protected edge states.
Critical points between obstructed atomic insulators in (2+1)D can realize stable QED3 when microscopic lattice symmetries suppress monopoles.
Analytical QFI calculations for finite-size spin chain at strong coupling show thermometry advantages at low T and large errors from neglecting FS effects or using phenomenological models.
Reports spontaneous continuous symmetry breaking and a tower of states in a 1D comb-chain antiferromagnet with short-range interactions, linked to the Marshall-Lieb-Mattis theorem.
A comprehensive review of scaling paths for superconducting quantum computers, with resource and sensitivity analyses for utility-scale applications under realistic error distributions.
