Generalized symmetry-protected topological phases in mixed states from gauging dualities
Linhao Li, Zhen Bi, Weiguang Cao
Decoherence in realistic quantum platforms motivates a mixed-state notion of topological phases of matter, including average symmetry-protected topological (ASPT) phases. Alongside…

Modulated symmetries from generalized Lieb-Schultz-Mattis anomalies
Hiromi Ebisu, Bo Han, Weiguang Cao
Symmetries rigidly delimit the landscape of quantum matter. Recently uncovered spatially modulated symmetries, whose actions vary with position, enable excitations with restricted…

Matrix product state classification of 1D multipole symmetry protected topological phases
Takuma Saito, Weiguang Cao, Bo Han +1
Spatially modulated symmetries are one of the new types of symmetries whose symmetry actions are position dependent. Yet exotic phases resulting from these spatially modulated symm…
