Chiral Central Charge from Real-Space Twist Operator Correlator
Yunlong Zang
Recent years have witnessed substantial progress in the entanglement-based characterization of quantum phases of matter, with growing interest in real-space formulas due to their t…
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…
Entanglement Measure Response to Modular Flow and Chiral Topological Phases
Yunlong Zang
Recent years have witnessed significant progress in the entanglement-based characterization of quantum phases of matter. The primary objects of interest are the reduced density mat…
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…
Detecting Quantum Anomalies in Open Systems
Yunlong Zang, Yingfei Gu, Shenghan Jiang
Symmetries and quantum anomalies serve as powerful tools for constraining complicated quantum many-body systems, offering valuable insights into low-energy characteristics based on…
