An Approximate Solution of the Master Equation with the Dissipator being a Set of Projectors
Kazuyuki Fujii
In this paper we consider a quantum open system and treat the master equation with some restricted dissipator which consists of a set of projection operators (projectors). The exac…

Exponentiation of certain Matrices related to the Four Level System by use of the Magic Matrix
Kazuyuki Fujii
In this paper we show how to calculate explicitly the exponential of certain matrices, which are evolution operators governing the interaction of the four level system of atoms and…
