Useful transformations: From ion-laser interactions to master equations
Raúl Juárez-Amaro, J. M. Vargas-Martínez, H. M. Moya-Cessa · Laser Physics · 2008
We show a set of transformations that allow one to obtain analytical solutions in several quantum-optical problems. We start with the ion-laser (time-dependent) interaction, continue with the problem of a slow atom interacting with a quantized field, and end with a master equation that describes the losses. In all cases, it is shown that one may find useful transformations that simplify the problems.
