Attractive Hubbard model and single-particle pseudogap due to classical pairing fluctuations in two dimensions
Y. M. Vilk, S. Allen, H. Touchette +3
It is shown that in the two-dimensional attractive Hubbard model, the mean-field phase transition is replaced by a renormalized classical regime of fluctuations where a pseudogap o…

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…
