Effect of Induced Gauge Field in Jaynes–Cummings Atom with Space-Dependent Coupling

En-Ke Tian, Chang-Pu Sun

The effect of the motion of mass center of a two-level atom on its transition in a quantized radiation field is studied in this paper by generalizing the Jaynes–Cummings model to include the coupling depending on space degrees of freedom. As an additional geometrical phase—Berry's phase in the oscillation, the effect of the induced gauge field resulting from the Born–Oppenheimer (BO) approximation explicitly exists in the transition probability between the up and down states of atomic quasispin. It is shown that when the atom's kinetic energy is small enough that the BO adiabatic approximation holds for the case with small atom's momentum or large detuning, the adiabatically approximate solutions are applicable and it is possible to localize an atom in the cavity.The effect of the motion of mass center of a two-level atom on its transition in a quantized radiation field is studied in this paper by generalizing the Jaynes–Cummings model to include the coupling depending on space degrees of freedom.

Velocity-selective population and quantum collapse-revival phenomena of the atomic motion for a motion-quantized Raman-coupled Jaynes-Cummings model

Jiaren Liu, Yuzhu Wang

An extension of the standard Raman-coupled Jaynes-Cummings model has been made to include atomic external effects due to quantization of atomic motion. The collapse-and-revival phenomena in population inversion and in atomic motion, the velocity-selective population and their relation for a motion-quantized atom are given on the basis of a fundamental constant characterizing the interaction strength between the field modes and the atomic internal and external states. This study reveals how the initial statistics of atomic momentum affect the atomic internal dynamics and how those of the fields affect the atomic external dynamics through the atomic internal states. An exact expression for the time evolution of the density operator has been given for two fields and the center-of-mass motion initially in coherent states and in an arbitrary superposition of atomic momentum eigenstates. The statistics of atomic external and internal quantities such as the radiation force and the atomic momentum are given. \textcopyright{} 1996 The American Physical Society.An extension of the standard Raman-coupled Jaynes-Cummings model has been made to include atomic external effects due to quantization of atomic motion.
