Modulational instability of spinor condensates
Nicholas P. Robins, Weiping Zhang, Elena A. Ostrovskaya +1
We demonstrate, analytically and numerically, that the ferromagnetic phase of the spinor Bose-Einstein condenstate may experience modulational instability of the ground state leadi…
Bose-Einstein Condensates in Optical Lattices: Spontaneous Emission in the Presence of Photonic Band Gaps
Karl-Peter Marzlin, Weiping Zhang
An extended Bose-Einstein condensate (BEC) in an optical lattice provides a kind of periodic dielectric and causes band gaps to occur in the spectrum of light propagating through i…
Creation of Skyrmions in a Spinor Bose-Einstein Condensate
Karl-Peter Marzlin, Weiping Zhang, Barry C. Sanders
We propose a scheme for the creation of skyrmions (coreless vortices) in a Bose-Einstein condensate with hyperfine spin F=1. In this scheme, four traveling-wave laser beams, with G…
Spontaneous emission of polaritons from a Bose-Einstein condensate
Karl-Peter Marzlin, Weiping Zhang
We study the spontaneous emission of a partially excited Bose-Einstein condensate composed of two-level atoms. The formation of polaritons induced by the ground-state part of the c…
Weak force detection using a double Bose-Einstein condensate
J. F. Corney, G. J. Milburn, Weiping Zhang
A Bose-Einstein condensate may be used to make precise measurements of weak forces, utilizing the macroscopic occupation of a single quantum state. We present a scheme which uses a…
Bloch function description of a Bose-Einstein condensate in a finite optical lattice
M. J. Steel, Weiping Zhang
We consider stationary and propagating solutions for a Bose-Einstein condensate in a periodic optical potential with an additional confining optical or magnetic potential. Using an…
