Maintaining Coherence of a Two-level Atom in Motion Through an External Controllable Driving Field

Zhang Deng

Published Jan 1, 2003• 0 citations
OpenAlex

Abstract

The time evolution properties of non opposite angle element of two level atoms reducible density rectangular array was discussed.Coherence properties of two level atom was studied in one photon processes when the two level atom interacts with an driving field in the thermal radiation field.When two level atoms coherence is maintained,the theoretical result demonstrates that time evolution of an external driving field is closely related to atomic jump frequency,atomic motion velocity and the average of k modul photon number etc.
