Process chain approach to the Bose-Hubbard model: Ground-state properties and phase diagram
Niklas Teichmann, Dennis Hinrichs, Martin Holthaus +1
We carry out a perturbative analysis, of high order in the tunneling parameter, of the ground state of the homogeneous Bose-Hubbard model in the Mott insulator phase. This is made…

Bose-Hubbard phase diagram with arbitrary integer filling
Niklas Teichmann, Dennis Hinrichs, Martin Holthaus +1
We study the transition from a Mott insulator to a superfluid in both the two- and the three-dimensional Bose-Hubbard model at zero temperature, employing the method of the effecti…
