Local moment approach to multi-orbital single impurity Anderson model; application to dynamical mean-field theory
Anna Kauch, Krzysztof Byczuk
Using a local moment approach of Logan et al. we developed a solver for a multi-orbital single impurity Anderson model. The existence of the local moments is taken from the outset…

Green functions for nearest- and next-nearest-neighbor hopping on the Bethe lattice
M. Kollar, M. Eckstein, K. Byczuk +8
We calculate the local Green function for a quantum-mechanical particle with hopping between nearest and next-nearest neighbors on the Bethe lattice, where the on-site energies may…

Mott--Hubbard and Anderson Transitions in Dynamical Mean--Field Theory
Krzysztof Byczuk, Walter Hofstetter, Dieter Vollhardt
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…
