Revealing the superfluid–Mott-insulator transition in an optical lattice
Numerical solution of single particle the density matrix ultracold atomic optical lattice parabola mott insulator
2014/12/22
We study (by an exact numerical scheme) the single-particle density matrix of ～103 ultracold atoms in an optical lattice with a parabolic confining potential. Our simulation is directly relevant to th...
Effects of finite temperature on the Mott-insulator state
Temperature ultracold bose atoms optical lattice atom
2014/12/20
We investigate the effects of finite temperature on ultracold Bose atoms confined in an optical lattice plus a parabolic potential in the Mott-insulator state. In particular, we analyze the temperatur...
Absence of a Direct Superfluid to Mott Insulator Transition in Disordered Bose Systems
Quantum phase transition superfluid mott insulator bosonic system inclusions
2014/12/19
We prove the absence of a direct quantum phase transition between a superfluid and a Mott insulator in a bosonic system with generic, bounded disorder. We also prove the compressibility of the system ...
