Classification of phases for mixed states via fast dissipative evolution
We propose the following definition of topological quantum phases valid for mixed states: two states are in the same phase if there exists a time independent, fast and local Lindbladian evolution driving one state into the other. The underlying idea, motivated by \cite{Konig2014}, is that it takes t...
