-type Lieb-Schultz-Mattis anomalies, deconfined quantum critical points, and non-invertible symmetry breaking
Hao-Ran Zhang, Hanlin Lin, Shuo Yang +1
We study deconfined quantum critical points (DQCP) associated with Lieb-Schultz-Mattis (LSM) anomalies in one-dimensional spin chains. Our starting point is a structural characteri…
Strong-to-weak spontaneous symmetry breaking meets average symmetry-protected topological order
Yuchen Guo, Shuo Yang
Recent studies have unveiled new possibilities for discovering intrinsic quantum phases that are unique to open systems, including phases with average symmetry-protected topologica…
Unveiling Stripe-shaped Charge Density Modulations in Doped Mott Insulators
Ning Xia, Yuchen Guo, Shuo Yang
Inspired by recent experimental findings, we investigate various scenarios of the doped Hubbard model with impurity potentials. We calculate the lattice Green's function in a finit…
Locally Purified Density Operators for Symmetry-Protected Topological Phases in Mixed States
Yuchen Guo, Jian-Hao Zhang, Hao-Ran Zhang +2
We propose a tensor network approach known as the locally purified density operator (LPDO) to investigate the classification and characterization of symmetry-protected topological…
