triqs.atom_diag.atom_diag

Lightweight exact diagonalization solver

Functions

act Act with operator op on state st
atomic_density_matrix The atomic density matrix
atomic_g_iw The atomic Matsubara Green's function, possibly with excluded states (none by default)
atomic_g_l The atomic Green's function in Legendre representation, possibly with excluded states (none by default)
atomic_g_tau The atomic imaginary time Green's function, possibly with excluded states (none by default)
atomic_g_w The atomic real frequency Green's function, possibly with excluded states (none by default)
partition_function The atomic partition function
quantum_number_eigenvalues Compute values of a given quantum number for all eigenstates
quantum_number_eigenvalues_checked Compute values of a given quantum number for all eigenstates, checking that op is a quantum number indeed.
trace_rho_op Compute Tr (op * density_matrix)
