Local Moment Approach to Multi-Orbital Anderson and Hubbard Models
The variational local moment approach (V-LMA), being a modification of the method due to Logan et al., is presented here. The existence of local moments is taken from the outset and their values are determined th...

Open AccessElectron-light interaction in nonequilibrium: exact diagonalization for time-dependent Hubbard Hamiltonians
We present a straightforward implementation scheme for solving the time-dependent Schrödinger equation for systems described by the Hubbard Hamiltonian with time-dependent hop**s. The computations can be per...

Open AccessThe plain and simple parquet approximation: single-and multi-boson exchange in the two-dimensional Hubbard model
The parquet approach to vertex corrections is unbiased but computationally demanding. Most applications are therefore restricted to small cluster sizes or rely on various simplifying approximations. We have re...
