Titre |
A unique non-Fermi liquid and high Tc superconductivity |
|
Résumé |
We present a simple model of fermions with repulsive quartic interactions in two dimensions that has non-Fermi liquid behavior
due to a low energy fixed point. Incorporating momentum dependent
scattering of Cooper pairs we derive a new gap equation, and show that
an attractive d-wave channel opens up at 1-loop.
The main features of the phase diagram can be calculated as a function
of doping by solving 2 gap equations. The wave pairing falls under
a superconducting dome, which terminates at the renormalization
group fixed point. The pseudogap energy scale is identified
with the scale of the coupling strength of the interaction. |
