Photonic band gaps and defect states induced by excitations of Bose-Einstein condensates in optical lattices
Karl-Peter Marzlin, Weiping Zhang
We study the interaction of a Bose-Einstein condensate, which is confined in an optical lattice, with a largely detuned light field propagating through the condensate. If the conde…
Acceleration of quasi-particle modes in Bose-Einstein condensates
Karl-Peter Marzlin, Weiping Zhang
We analytically examine the dynamics of quasi-particle modes occuring in a Bose-Einstein condensate which is subject to a weak acceleration. It is shown that the momentum of a quas…
Quantized circular motion of a trapped Bose-Einstein condensate: coherent rotation and vortices
Karl-Peter Marzlin, Weiping Zhang
We study the creation of vortex states in a trapped Bose-Einstein condensate by a rotating force. For a harmonic trapping potential the rotating force induces only a circular motio…
Laser-induced Rotation of a Trapped Bose-Einstein Condensate
Karl-Peter Marzlin, Weiping Zhang
In this letter, atom optic techniques are proposed to control the excitation of a Bose-Einstein condensate in an atomic trap. We show that by employing the dipole potential induced…
