Instability of steady-state mixed-state symmetry-protected topological order to strong-to-weak spontaneous symmetry breaking
Jeet Shah, Christopher Fechisin, Yu-Xin Wang +6
Recent experimental progress in controlling open quantum systems enables the pursuit of mixed-state nonequilibrium quantum phases. We investigate whether open quantum systems hosti…

Non-invertible symmetry-protected topological order in a group-based cluster state
Christopher Fechisin, Nathanan Tantivasadakarn, Victor V. Albert
Despite growing interest in beyond-group symmetries in quantum condensed matter systems, there are relatively few microscopic lattice models explicitly realizing these symmetries,…
