Interaction free and decoherence free states
An interaction free evolving state of a closed bipartite system composed of two interacting subsystems is a generally mixed state evolving as if the interaction were a c-number. In this paper we find the characteristic equation of states possessing similar properties for a bipartite systems governed...

| description | An interaction free evolving state of a closed bipartite system composed of
two interacting subsystems is a generally mixed state evolving as if the
interaction were a c-number. In this paper we find the characteristic equation
of states possessing similar properties for a bipartite systems governed by a
linear dynamical equation whose generator is sum of a free term and an
interaction term. In particular in the case of a small system coupled to its
environment, we deduce the characteristic equation of decoherence free states
namely mixed states evolving as if the interaction term were effectively
inactive. Several examples illustrate the applicability of our theory in
different physical contexts. |
