Perturbative calculation of critical exponents for the Bose-Hubbard model
Dennis Hinrichs, Axel Pelster, Martin Holthaus
We develop a strategy for calculating critical exponents for the Mott insulator-to-superfluid transition shown by the Bose-Hubbard model. Our approach is based on the field-theoret…
Reference data for phase diagrams of triangular and hexagonal bosonic lattices
Niklas Teichmann, Dennis Hinrichs, Martin Holthaus
We investigate systems of bosonic particles at zero temperature in triangular and hexagonal optical lattice potentials in the framework of the Bose-Hubbard model. Employing the pro…
Scaling property of the critical hopping parameters for the Bose-Hubbard model
Niklas Teichmann, Dennis Hinrichs
Recently precise results for the boundary between the Mott insulator phase and the superfluid phase of the homogeneous Bose-Hubbard model have become available for arbitrary intege…
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…
