Functions to calculate the total electron density of lattice Green’s functions using different methods and methods for chemical potenital searching given a target density.

Calculate the total electronic density from the lattice Green’s function and search for the chemical potential that gives a target electron count. We provide several algorithms optimized for speed and robustness. Due to the modularity you can also leverage external root finding routines to write a custom chemical potential search.

Functions

density	Compute the density of the lattice Green's function with a self-energy using Woodbury.
density_nk	Compute number of particles \(n = \sum f(\beta(\varepsilon(k) - μ))\).
find_chemical_potential	Find the chemical potenital from the local Green's function given a target density.
