First- and second-order superfluid--Mott-insulator phase transitions of spin-1 bosons with coupled ground states in optical lattices
K. V. Krutitsky, M. Timmer, R. Graham
We investigate the superfluid--Mott-insulator quantum phase transition of spin-1 bosons in an optical lattice created by pairs of counterpropagating linearly polarized laser beams,…
Spin-1 bosons with coupled ground states in optical lattices
K. V. Krutitsky, R. Graham
The superfluid--Mott-insulator phase transition of ultracold spin-1 bosons with ferromagnetic and antiferromagnetic interactions in an optical lattice is theoretically investigated…
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…
Local-field effect in atom optics of two-component Bose-Einstein condensates
K. V. Krutitsky, K. -P. Marzlin, J. Audretsch
Starting from the first principles of nonrelativistic QED we have developed the quantum theory of the interaction of a two-component ultracold atomic ensemble with the electromagne…
