Jahn-Teller induced Berry phase in spin-orbit coupled Bose-Einstein condensates
Jonas Larson, Erik Sjoqvist
We demonstrate that Berry phases may greatly affect the dynamics of spin-orbit coupled Bose-Einstein condensates. The effective model Hamiltonian under consideration is shown to be…
Quantum fluctuations in the mazer
Jonas Larson
Quantum fluctuations in the mazer are considered, arising either from the atomic motion or from the quantized intracavity field. Analytical results, for both the meza and the hyper…
Jahn-Teller systems from a cavity QED perspective
Jonas Larson
Jahn-Teller systems and the Jahn-Teller effect are discussed in terms of cavity QED models. By expressing the field modes in a quadrature representation, it is shown that certain s…
Cold Fermi atomic gases in a pumped optical resonator
Jonas Larson, Giovanna Morigi, Maciej Lewenstein
We study systems of fully polarized ultracold atomic gases obeying Fermi statistics. The atomic transition interacts dispersively with a mode of a standing-wave cavity, which is co…
Quantum interference structures in trapped ion dynamics beyond the Lamb-Dicke and rotating wave approximations
Dong Wang, Tony Hansson, Asa Larson +2
We apply wave packet methods to study an ion-trap system in the strong excitation regime imposing neither the rotating wave nor the Lamb-Dicke approximations. By this approach we s…
