Paolo Aniello, Andrzej Kossakowski, Giuseppe Marmo, F. Ventriglia, Patrizia Vitale · Open Systems & Information Dynamics · 2010
A new method to deal with reduced dynamics of open systems by means of the Schrödinger equation is presented. It allows one to consider the reduced time evolution for correlated and uncorrelated initial conditions.
