Electromagnetic response of time-reversal breaking metallic phases in two dimensions
… the critical point we have is similar to that of Pomeranchuk instability. The quartic term in the dispersion expansion needed to be introduced to stabilize the theory. The correction coming from the higher order terms introduces the coupling to the curvature of the Fermi surfaces. The beta phase …

Non-perturbative approaches to strongly correlated electron systems
"Strong electron correlation phenomena are ubiquitous, such as unconventional superconductivity and the metal-insulator transitions. Having a proper understanding of strongly correlated electron systems requires a non-perturbative analysis because Fermi liquid theory inevitably breaks down due to …
