Sound speed of a Bose-Einstein condensate in an optical lattice
Z. X. Liang, Xi Dong, Z. D. Zhang +1
The speed of sound of a Bose-Einstein condensate in an optical lattice is studied both analytically and numerically in all three dimensions. Our investigation shows that the sound…

Bragg spectroscopy of a superfluid Bose-Hubbard gas
X. Du, Shoupu Wan, Emek Yesilada +4
Bragg spectroscopy is used to measure excitations of a trapped, quantum-degenerate gas of 87Rb atoms in a 3-dimensional optical lattice. The measurements are carried out over a ran…
