Gaplessness indicator by topologically trivial twisting operators
Yuan Yao, Linhao Li, Feng-Feng Song
We propose several general necessary conditions for quantum many-body system in one dimension respecting U(1) symmetry to be gapped. We show that the ground-state expectation value…
Exact Quantum Many-Body Scars in 2D Quantum Gauge Models
Yuan Miao, Linhao Li, Hosho Katsura +1
The paper identifies exact quantum many-body scar states in a two‑dimensional Z₂ gauge model by exploiting its duality to a spin‑½ XY model on bipartite graphs, showing that these…
Generalized Kramers-Wannier Duality from Bilinear Phase Map
Linhao Li, Masaki Oshikawa, Han Yan
We present the bilinear phase map (BPM), a concept that generalizes the Kramers-Wannier (KW) transformation to investigate unconventional gapped phases of qudit spin chains. Encodi…
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…
Mixed-State Topological Phase: Quantized Topological Order Parameter and Lieb-Schultz-Mattis Theorem
Linhao Li, Yuan Yao
We investigate the extension of pure-state symmetry protected topological phases to mixed-state regime with a strong U(1) and a weak symmetries in one-dimensional sp…
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…
