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…
A New Framework for Quantum Phases in Open Systems: Steady State of Imaginary-Time Lindbladian Evolution
Yuchen Guo, Ke Ding, Shuo Yang
This study delves into the concept of quantum phases in open quantum systems, examining the shortcomings of existing approaches that focus on steady states of Lindbladians and high…
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…
