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…

Matrix Product States for Modulated Symmetries: SPT, LSM, and Beyond
Amogh Anakru, Linhao Li, Sarvesh Srinivasan +1
Matrix product states (MPS) provide a powerful framework for characterizing one-dimensional symmetry-protected topological (SPT) phases of matter and for formulating Lieb-Schultz-M…
