Löwdin's symmetry dilemma within Green functions theory for the one-dimensional Hubbard model
J. -P. Joost, N. Schlünzen, S. Hese +4
The energy gap of correlated Hubbard clusters is well studied for one-dimensional systems using analytical methods and density-matrix-renormalization-group (DMRG) simulations. Beyo…

The G1--G2 Scheme: Dramatic Acceleration of Nonequilibrium Green Functions Simulations Within the Hartree--Fock-GKBA
J. -P. Joost, N. Schlünzen, M. Bonitz
The time evolution in quantum many-body systems after external excitations is attracting high interest in many fields. The theoretical modeling of these processes is challenging, a…
