Series solution to the laser-ion interaction in a Raman-type configuration

Mang Feng

The Raman interaction of a trapped ultracold ion with two travelling wave lasers is studied analytically with series solutions, in the absence of the rotating wave approximation (R…

AC-driven quantum spins: resonant enhancement of transverse DC magnetization

S. Flach, A. E. Miroshnichenko, A. A. Ovchinnikov

We consider s=1/2 spins in the presence of a constant magnetic field in z-direction and an AC magnetic field in the x-z plane. A nonzero DC magnetization component in y direction i…

Atomic scattering from Bose-Einstein condensates

Ivo Haering, Jan M Rost

Elastic scattering probes directly the interaction potential. For weakly interacting condensates this potential is given by the condensate density. We investigate how the different…

Weak localization of light by cold atoms: the impact of quantum internal structure

Cord A. Mueller, Thibaut Jonckheere, Christian Miniatura +1

Since the work of Anderson on localization, interference effects for the propagation of a wave in the presence of disorder have been extensively studied, as exemplified in coherent…

Correlations in quantum systems and branch points in the complex plane

I. Rotter

Branch points in the complex plane are responsible for avoided level crossings in closed and open quantum systems. They create not only an exchange of the wave functions but also a…

Complete solution of the Schrödinger equation for the time-dependent linear potential

Mang Feng

The complete solutions of the Schrödinger equation for a particle with time-dependent mass moving in a time-dependent linear potential are presented. One solution is based on the w…
