Time-dependent nonlinear Jaynes-Cummings dynamics of a trapped ion
Fabian Krumm, Werner Vogel
In quantum interaction problems with explicitly time-dependent interaction Hamiltonians, the time ordering plays a crucial role for describing the quantum evolution of the system u…
High-order nonlinearities in the motion of a trapped atom
S. Wallentowitz, W. Vogel, P. L. Knight
We study the counterpart to the multi-photon down conversion in the quantised motion of a trapped atom. The Lamb-Dicke approximation leads to a divergence of the mean motional exci…
Determination of entangled quantum states of a trapped atom
S. Wallentowitz, R. L. de Matos Filho, W. Vogel
We propose a method for measuring entangled vibronic quantum states of a trapped atom. It is based on the nonlinear dynamics of the system that appears by resonantly driving a weak…
Quantum mechanical counterpart of nonlinear optics
S. Wallentowitz, W. Vogel
Raman-type laser excitation of a trapped atom allows one to realize the quantum mechanical counterpart of phenomena of nonlinear optics, such as Kerr-type nonlinearities, parametri…
