Elementary open quantum states
Janos Polonyi, Ines Rachid
It is shown that the mixed states of a closed dynamics support a reduplicated symmetry, which is reduced back to the subgroup of the original symmetry group when the dynamics is op…

Electric current in a translation invariant environment
Janos Polonyi, Ines Rachid
The master equation for the reduced density matrix of a charged particle interacting with a translation invariant weakly coupled environment is considered. The electric current is…
