Nonlinear polaritons in Bose-Einstein condensates in optical lattices
arXiv:nlin/0311007 · doi:10.1117/12.561013
Abstract
We study the interaction of a Bose-Einstein condensate in an optical lattice with additional electromagnetic fields under Raman resonance condition. System of evolution equations describing ultra-short optical pulse propagation and photo-induced transport of cold atoms in optical lattice is derived. The steady state solution of these equations was found. There are new kinds of polaritonic solitary waves propagating.
