M. Caffarel, W. Krauth Exact Diagonalization Approach to Correlated Fermions in Infinite Dimensions: Mott Transition and Superconductivity Physical Review Letters 72 1545 (1994)
Context: In this paper, we proposed an exact diagonalization method for the solution of the single-impurity method which has proven useful in a number of contexts.
See here for exact-diagonalization programs at zero temperature (Lanczos) and at finite temperature.
