From Topological Order to Mixed-State Phases: A Ground-State Probe of Fractionalized Excitations
Yunlong Zang, Yu-Bin Li, Shenghan Jiang
How do we detect topological phases from a single ground state? Entanglement entropy and spectrum have long been the standard tools -- but the reduced density matrix (RDM) itself c…

Measurement protocol for detecting correlated topological insulators in synthetic quantum systems
Yixin Ma, Chao Xu, Shenghan Jiang
Two-dimensional topological insulators, characterized by symmetry-protected anomalous boundary modes, have been generalized to the strongly correlated regime for both bosonic and f…

Diagnosing 2D symmetry protected topological states via mixed state anomaly
Chao Xu, Yunlong Zang, Yixin Ma +2
Symmetry-protected topological (SPT) phases are short-range entangled quantum states characterized by anomalous edge behavior, a manifestation of the bulk-boundary correspondence f…
