Nonequilibrium topological response under charge dephasing

Aps.org·September 24, 2026

We explore nonequilibrium topological responses of symmetry-protected topological (SPT) states in open quantum systems subject to decoherence. For SPT wave functions protected by a product symmetry $G\ifmmode\times\else\texttimes\fi{}S$, where $G$ defects are…
