gmp007/dmft-lanc-ed

Lanczos based Exact Diagonalization solver for the Dynamical Mean-Field Theory problem. This code is implemented in the (N_up:N_dw) basis and solves the Normal phase only.

DMFT Lanczos Exact Diagonalization

A Lanczos based solver for the Dynamical Mean-Field Theory using the N_up:N_dw implementation.
This code solves the normal (N_up, N_dw) case only. (For a generic implemenation which allows for superconductivity (s-wave) or SOC see here: https://github.com/aamaricci/dmft-ed

The code is based on:

• SciFortran https://github.com/aamaricci/SciFortran

• DMFT_Tools https://github.com/aamaricci/DMFTtools [For the driver part, see below]

The code structure is as follow:

• The set of modules compile into a top layer named DMFT_ED.f90
• The actual implementation of the DMFT equations is case by case performed in a driver program, usually placed in the directory drivers.
• In the driver code the user must includes the DMFT_ED module and call the necessary procedures to solve the DMFT equations.

An example, solving the Hubbard model on the Bethe lattice, is contained in the file drivers/edn_hm_bethe.f90.
