Real-time evolution of the GS of the U=0 Fermi-Hubbard model
Dear Johannes, I am running some real-time evolution simulations in TeNpy. First, I simply find the GS of the U=0 Fermi-Hubbard model using infinite DMRG. This is a gapless state, so I cannot fully get a converged result, but I get convergence to three digits in the energy if I use chi=200. Then, I ...
