Properties of the State of the Atoms Trapped Coherently

Xiaoping Li

Published Jan 1, 2006• 0 citations
OpenAlex

Abstract

That the atoms are trapped coherently in the system of two coupled-atoms Raman-interacting with a single-mode squeezed vacuum field is studied by means of quantum theory.The results indicate that the atoms' state is a pure state which is different from its initial state,and the disentanglement between atoms and field arises provided that the atoms are trapped coherently.
