Topologically Ordered Steady States in Open Quantum Systems

He-Ran Wang, Xu-Dong Dai, Zhong Wang, Zijian Wang

Steady-state topological degeneracy in open quantum systems is stable in three dimensions but fragile in two.

Claims

C1strongest claim

while the steady-state topological degeneracy is fragile under noise in two dimensions, it is stable in three dimensions, where a genuine many-body phase with topological degeneracy is realized

C2weakest assumption

The two representative Liouvillians constructed via engineered dissipation admit exact solutions whose steady states carry the claimed topological degeneracy (abstract, paragraph 2).

C3one line summary

Engineered dissipation produces topologically degenerate steady states that form a stable many-body phase in three dimensions but not two.
