DMRG study of the spin gap in a one dimensional Hubbard model: effect of the distant transfer and exchange coupling

Ryotaro Arita, Kazuhiko Kuroki, Hideo Aoki +1

The spin gap of a one-dimensional repulsive Hubbard model is numerically calculated with the density matrix renormalization group, with a special emphasis on the effect of a next-n…
