Record completeness
Claims
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
The two representative Liouvillians constructed via engineered dissipation admit exact solutions whose steady states carry the claimed topological degeneracy (abstract, paragraph 2).
Engineered dissipation produces topologically degenerate steady states that form a stable many-body phase in three dimensions but not two.
