Phase Transitions in Dissipative Quantum Transport and Mesoscopic Nuclear Spin Pumping

By M. Rudner and L. Levitov
Topological phase transitions can occur in the dissipative dynamics of a quantum system when the ratio of matrix elements for competing transport channels is varied. Here we establish a relation between such behavior in a class of non-Hermitian quantum walk problems [M. S. Rudner and L. S. Levitov, Phys. Rev.... Show more
