Effect of next-nearest-neighbour hopping on BoseEinstein condensation in optical lattices
Overview & Synopsis
We study the influence of the various hopping elements on the ground state properties of the bosons in the 2D optical square lattice. Using the quantum rotor approach for the Bose-Hubbard model with nearest t and next nearest-neighbours t ? hopping, we quantify to what extent changing the ratio t ? /t affects the superfluid to Mott-insulator transition.
