Functions

conjugate(x)	Return the conjugate of a Green's function
delta(g)	Compute Delta_iw from G0_iw. CAUTION: This function assumes the following properties of g * The diagonal components of g should decay as 1/iOmega * g should fullfill the property g[iw][i,j] = conj(g[-iw][j,i]).
discretize_bath(delta_in, Nb[, eps0, V0, ...])	Discretize a given hybridization function using Nb bath sites.
dyson(**kwargs)	Solve Dyson's equation for given two of G0_iw, G_iw and Sigma_iw to yield the third.
fit_legendre(g_t[, order])	General fit of a noisy imaginary time Green's function to a low order Legendre expansion in imaginary time.
inverse(x)	Return the inverse of its argument, with proper treatement of lazy expressions.
make_delta(V, eps, mesh[, block_names])	Create a hybridization function from given hoppings and bath energies as .
make_zero_tail(g[, n_moments])	Return a container for the high-frequency coefficients of a given Green function initialized to zero.
read_gf_from_txt(block_txtfiles, block_name)	Read a GfReFreq from text files with the format (w, Re(G), Im(G)) for a single block.
transpose(x)	Return the transpose of a Green's function
write_gf_to_txt(g)	Write a GfReFreq or GfImFreq to in the format (w/iw, Re(G), Im(G)) for a single block.
