Strong-to-Weak Symmetry Breaking Phases in Steady States of Quantum Operations
Niklas Ziereis, Sanjay Moudgalya, Michael Knap
Mixed states can exhibit two distinct kinds of symmetries, either on the level of the individual states (strong symmetry), or only on the level of the ensemble (weak symmetry). Str…

Light-driven interlayer propagation of collective-mode excitations in layered superconductors
Niklas Ziereis, Kazuaki Takasan, Naoto Tsuji
Superconductors exhibit a nonlinear interaction with an applied light, which can resonantly excite the collective amplitude (Higgs) mode. Here we study light-induced dynamics of la…
