Non-perturbative many-body approach to the Hubbard model and single-particle pseudogap
Y. M. Vilk, A. -M. S. Tremblay
A new approach to the single-band Hubbard model is described in the general context of many-body theories. It is based on enforcing conservation laws, the Pauli principle and a num…
