Mesoscopic Effects in Quantum Phases of Ultracold Quantum Gases in Optical Lattices
L. D. Carr, M. L. Wall, D. G. Schirmer +3
We present a wide array of quantum measures on numerical solutions of 1D Bose- and Fermi-Hubbard Hamiltonians for finite-size systems with open boundary conditions. Finite size eff…
Quantum phases of bosons in double-well optical lattices
Ippei Danshita, James E. Williams, Carlos A. R. Sa de Melo +1
We study the superfluid to Mott insulator transition of bosons in a two-legged ladder optical lattice, of a type accessible in current experiments on double-well optical lattices.…
Linear spin waves in a trapped Bose gas
T. Nikuni, J. E. Williams, C. W. Clark
An ultra-cold Bose gas of two-level atoms can be thought of as a spin-1/2 Bose gas. It supports spin-wave collective modes due to the exchange mean field. Such collective spin osci…
