Separability transitions in topological states induced by local decoherence
YH Chen, T Grover - Physical Review Letters, 2024 - APS
We study states with intrinsic topological order subjected to local decoherence from the
perspective of separability, ie, whether a decohered mixed state can be expressed as an …
