Impurity Model Bath
Bath Auxiliary
In this set of modules we implement a number of auxiliary procedures
which are required to enumerate the bath levels, performs all the
relevant checks on the user input bath, build up of the
replica/general matrix basis or apply given symmetry operation
on the user side.
Bath DMFT
In ed_bath_dmft we implement operations on the effective_bath data
structure: a suitable representation of the effective bath used
internally in the code. We refer to the generic shared instance of this bath
as dmft_bath. Depending on the value bath_type this quantity collect
different bath parameters which can be directly accessed in the
construction of symmetry sectors Hamiltonian.
Bath Functions
In ed_bath_functions we implement on-the-fly construction of
the hybridization functions \(\Delta(z) = \sum_p
\hat{V}^p\left[z-\hat{h}^p \right]^{-1}\hat{V}^p\), as well as of the
non-interacting Anderson Green’s functions
\(G_0(z) = \left[z +\mu - H_{loc} - \Delta(z) \right]^{-1}\) for
all different cases selected by ed_mode and bath_type.
