Solvable non-Hermitian skin effect in many-body unitary dynamic
Solvable non-Hermitian skin effect in many-body unitary dynamic
Studying unitary evolution of bipartite entanglement in a circuit with nearest-neighbor random gates we show that being exact is actually wrong, while being slightly wrong is correct. Deriving a non-unitary description of purity dynamics on qudits we find a transition in the purity relaxation rate whose origin is in the …
