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…

Field Theory And Second Renormalization Group For Multifractals In Percolation
B. Fourcade, Jean Perrin
The field-theory for multifractals in percolation is reformulated in such a way that multifractal exponents clearly appear as eigenvalues of a second renormalization group. The fir…
