Abstract
Complex potentials have been used previously to simulate dissipative proces ses in quantum simulations of transport and scattering. A general formulati on is presented which shows how such non-Hermitian terms can lead to change s in the dynamics of transport operators, and to the decay of hydrodynamic quantities such as phase, energy, and momentum.
