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…

Operator Size Distribution in Large Quantum Mechanics of Majorana Fermions
Pengfei Zhang, Yingfei Gu
Under the Heisenberg evolution in chaotic quantum systems, initially simple operators evolve into complicated ones and ultimately cover the whole operator space. We study the growt…
