One-electron spectral functions of the attractive Hubbard model at intermediate coupling
M. Yu. Kagan, R. Fresard, M. Capezzali +1
We calculate the one-electron spectral function of the attractive-U Hubbard model in two dimensions. We work in the intermediate coupling and low density regime and evaluate analyt…

Critical temperature and phase diagram for a 2D superfluid Fermi-gas with repulsion
D. V. Efremov, M. S. Mar'enko, M. A. Baranov +1
In the framework of a 2D Fermi-gas with short-range repulsive interaction we find the critical temperature of the superfluid phase transition based on Kohn-Luttinger effect, and an…

Phase diagram of three-leg ladders at strong coupling along the rungs
Maxim Yu. Kagan, Stephan Haas, T. M. Rice
A phase diagram of the t-J three-leg ladder as a function of hole dopping is derived in the limit where the coupling parameters along the rungs, and , are ta…
