Resonant Generation of Topological Modes in Trapped Bose Gases
V. I. Yukalov, K. -P. Marzlin, E. P. Yukalova
Trapped Bose atoms cooled down to temperatures below the Bose-Einstein condensation temperature are considered. Stationary solutions to the Gross-Pitaevskii equation (GPE) define t…
Stability of gap solitons in a Bose-Einstein condensate
Karen Marie Hilligsoe, Markus K. Oberthaler, Karl-Peter Marzlin
We analyze the dynamical stability of gap solitons formed in a quasi one-dimensional Bose-Einstein condensate in an optical lattice. Using two different numerical methods we show t…
Ultracold Bose atoms in intense laser fields: intensity- and density-dependent effects
K. V. Krutitsky, K. -P. Marzlin, J. Audretsch
Starting from the first principles of nonrelativistic QED we have derived the system of Maxwell-Schrödinger equations, which can be used for theoretical description of atom optical…
