Quasi-relativistic behavior of cold atoms in light fields
G. Juzeliunas, J. Ruseckas, M. Lindberg +2
We study the influence of three laser beams on the center of mass motion of cold atoms with internal energy levels in a tripod configuration. We show that similar to electrons in g…
Formation of solitons in atomic Bose-Einstein condensates by dark-state adiabatic passage
G. Juzeliunas, J. Ruseckas, P. Öhberg +1
We propose a new method of creating solitons in elongated Bose-Einstein Condensates (BECs) by sweeping three laser beams through the BEC. If one of the beams is in the first order…
Trading activity as driven Poisson process: comparison with empirical data
V. Gontis, B. Kaulakys, J. Ruseckas
We propose the point process model as the Poissonian-like stochastic sequence with slowly diffusing mean rate and adjust the parameters of the model to the empirical data of tradin…
Polarisation rotation of slow light with orbital angular momentum in ultracold atomic gases
J. Ruseckas, G. Juzeliunas, P. Ohberg +1
We consider the propagation of slow light with an orbital angular momentum (OAM) in a moving atomic medium. We have derived a general equation of motion and applied it in analysing…
