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…
Local-field effects in radiatively broadened magneto-dielectric media: negative refraction and absorption reduction
Jürgen Kästel, Michael Fleischhauer, Gediminas Juzeliūnas
We give a microscopic derivation of the Clausius-Mossotti relations for a homogeneous and isotropic magneto-dielectric medium consisting of radiatively broadened atomic oscillators…
