We reveal that the nonreciprocal current appears in a dissipative system through interband processes. We derive a formula for the nonreciprocal current using the Green's function technique. The nonreciprocal current of the present mechanism turns out to be of $O(1/\\tau)$ ($\\tau$: the lifetime of Bloch electrons) and arises from the shift of the electron wave packet during the interband processes which has a geometric origin. We present a numerical simulation of the nonreciprocal current in the "},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"We show that the nonreciprocal current appears in a dissipative system through interband processes.
