Description
We study the Lieb-Schultz-Mattis anomaly in Majorana chains with dissipation.
In Hamiltonian systems, Majorana translations flow to chiral fermion parity symmetries in the continuum limit.
In this talk, we investigate the relation between Majorana translations and chiral fermion parity in open quantum systems.
We present an anomaly among weak and strong symmetries that is peculiar to open Majorana chain models.
We also present a concrete quantum master equation (Lindblad equation) with strong Majorana translation symmetry and the effects of anomalies on the spectrum of the Liuville operators.
