gem.solvers.solver_template.SolverTemplate

class gem.solvers.solver_template.SolverTemplate(norb, use_Ntot=False, use_Sz=False, thermal=False, solver_params=None)

Your class aim to solve general impurity Hamiltonian.

Methods

calc_density_matrix()	Compute denstiy matrix. Return: denmat: numpy.array. Densty matrix, <c^dagger_i c_j>, of the system (impurity+bath).
compute_E1loc(eloc[, mu])	Compute the local one-body energy E1loc = Tr[eloc * denmat_impurity] Return: E1loc: float. Local one-body energy.
compute_E2loc(eloc, D, Lambdac[, mu])	Compute local energy including local one and two-body term from a given set od thermal states Works also at zero Temperature Input: Return: Eloc: float. Total local energy.
solve_Hemb([num_eig, verbose, tol, T])	diagonalize the Hamiltonian.
