Auxiliary Functions

Description

Hosts a number of auxiliary procedures required in different parts of the code. Specifically, it implements: creation/annihilation fermionic operators, binary decomposition of integer representation of Fock states and setup the local impurity Hamiltonian

Subroutines and functions

interface  e2i_aux_funx/ed_set_hloc(hloc, nlat)

This subroutine sets the local Hamiltonian of the impurity problem. The local hamiltonian can have different shapes:

• [nlat. nspin . norb, nlat. nspin . norb ]: real-space DMFT case, rank-2 array.

• [nlat , nspin . norb , nspin . norb ]: real-space RDMFT case, rank-3 array.

• [nlat , nspin , nspin , norb , norb ]: real-space RDMFT case, rank-5 array.

In the case of real-space DMFT, the number of impurities nlat must be provided.

Parameters:

• hloc (various shapes) [complex, in]

• nlat [integer] – Number of impurities for real-space DMFT
