‘‘Freely’’ falling two-level atom in a running laser wave
The time evolution of a two-level atom that is simultaneously exposed to the field of a running laser wave and a homogeneous gravitational field is studied. The result of the coupled dynamics of internal transitions and center-of-mass motion is worked out exactly. Neglecting spontaneous emission and performing the rotating-wave approximation, …
