A hazard of open quantum dynamics: Markov approximations encounter map domains
Thomas F. Jordan, Anil Shaji, E. C. G. Sudarshan
A Markov approximation in open quantum dynamics can give unphysical results when a map acts on a state that is not in its domain. This is examined here in a simple example, an open…

Maps and inverse maps in open quantum dynamics
Thomas F. Jordan
Two kinds of maps that describe evolution of states of a subsystem coming from dynamics described by a unitary operator for a larger system, maps defined for fixed mean values and…
