Decohering Kitaev's Sixteenfold Way: A Holographic Approach
Shuyu Zhang, Linhao Li, Zhen Bi +2
We study anyon decoherence in 2D topological order, with the fermion decoherence in Kitaev's sixteenfold way as explicit examples. The sixteenfold way includes chiral topological p…
Symmetry-Enforced Topological Structures in Quantum Phase Diagrams
Linhao Li, Yuan Yao
We study the topological structure of the quantum phase diagram of gapped systems by identifying the noncontractibility of loops, so-called -families, within the gapped phase…
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…
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…
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…
