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…
Hourglass-Like Spin Excitation in a Doped Mott Insulator
Jia-Xin Zhang, Chuan Chen, Jian-Hao Zhang +1
We examine the dynamical magnetic response in a two-component resonating-valence-bond (RVB) description of the doped Mott insulator. The half-filled antiferromagnetic phase describ…
