Dynamical mean field solution of the Bose-Hubbard model.
We present the effective action and self-consistency equations for the bosonic dynamical mean field approximation to the bosonic Hubbard model and show that it provides remarkably accurate phase diagrams and correlation functions. To solve the bosonic dynamical mean field equations, we use a continuous-time Monte Carlo method for bosonic impurity models based on a diagrammatic expansion in the ...
متن کاملStochastic mean-field theory for the disordered Bose-Hubbard model
We investigate the effect of diagonal disorder on bosons in an optical lattice described by an Anderson-Hubbard model at zero temperature. It is known that within Gutzwiller mean-field theory spatially resolved calculations suffer particularly from finite system sizes in the disordered case, while arithmetic averaging of the order parameter cannot describe the Bose glass phase for finite hoppin...
متن کاملDynamical mean - field theory for the normal phase of the attractive Hubbard model
We analyze the normal phase of the attractive Hubbard model within dy-namical mean-field theory. We present results for the pair-density, the spin-susceptibility, the specific heat, the momentum distribution, and for the quasi-particle weight. At weak coupling the low-temperature behavior of all quantities is consistent with Fermi liquid theory. At strong coupling all electrons are bound in pai...
متن کاملMott–Hubbard and Anderson Transitions in Dynamical Mean–Field Theory
The Anderson–Hubbard Hamiltonian at half–filling is investigated within dynamical mean–field theory at zero temperature. The local density of states is calculated by taking the geometric and arithmetic mean, respectively. The non–magnetic ground state phase diagrams obtained within the different averaging schemes are compared.
متن کاملCellular dynamical mean-field theory for the one-dimensional extended Hubbard model
We explore the use of exact diagonalization methods for solving the self-consistent equations of the cellular dynamical mean field theory for the one-dimensional regular and extended Hubbard models. We investigate the nature of the Mott transition and convergence of the method as a function of cluster size as well as the optimal allocation of computational resources between bath and ‘‘cluster-i...
