Effect of the lattice alignment on Bloch oscillations of a Bose-Einstein condensate in a square optical lattice
M. -C. Chung, A. R. Kolovsky
We consider a Bose-Einstein condensate of ultracold atoms loaded into a square optical lattice and subject to a static force. For vanishing atom-atom interactions the atoms perform…

Semiclassical quantization of the Bogoliubov spectrum
Andrey R. Kolovsky
We analyze the Bogoliubov spectrum of the 3-sites Bose-Hubbard model with finite number of Bose particles by using a semiclassical approach. The Bogoliubov spectrum is shown to be…
