Bosons in Disordered Optical Potentials
Pearl J. Y. Louis, Makoto Tsubota
In this work we systematically investigate the condensate properties, superfluid properties and quantum phase transitions in interacting Bose gases trapped in disordered optical po…
Dispersion control for matter waves and gap solitons in optical superlattices
Pearl J. Y. Louis, Elena A. Ostrovskaya, Yuri S. Kivshar
We present a numerical study of dispersion manipulation and formation of matter-wave gap solitons in a Bose-Einstein condensate trapped in an optical superlattice. We demonstrate a…
Dark Matter-Wave Solitons in Optical Lattices
Pearl J. Y. Louis, Elena A. Ostrovskaya, Yuri S. Kivshar
We analyze the Floquet-Bloch matter-wave spectrum of Bose-Einstein condensates loaded into single-periodic optical lattices and double-periodic superlattices. In the framework of t…
Bose-Einstein Condensates in Optical Lattices: Band-Gap Structure and Solitons
Pearl J. Y. Louis, Elena A. Ostrovskaya, Craig M. Savage +1
We analyze the existence and stability of spatially extended (Bloch-type) and localized states of a Bose-Einstein condensate loaded into an optical lattice. In the framework of the…
