12:30 pm:

One of the typical low-temperature phases of fermionic matter is

described by a phenomenological theory called Landau Fermi liquid.

I will be discussing the first proposed exactly solvable

microscopic theories which behave at low energies as Landau Fermi liquid.

These theories are the large-N three-dimensional Chern-Simons-fermion

and Thirring models. I will demonstrate how the three-dimensional

large-N power allows one to obtain exact results, at any value of the coupling

constant, for a number of interesting observables.
