Two Level Atom in Bichromatic Field: Von Neumann Entropy and Laser Cooling

ORAL

Abstract

We present the analysis of entropy flow during the two-level atomic interaction with a bichromatic field in the absence of spontaneous emission. Jaynes Cummings approach was used to develop the numerical model describing the system. The two mode field was detuned from atomic transition. Our calculation for flow characterizes improvement in Carnot's efficiency for laser cooling. This suggests efficient cooling of atom over a wide range of temperature and thus may give a whole new dimension to the field of laser cooling.
