Some Properties of Unitary Fermi Gas from the Epsilon Expansion
Andrei Kryjevski (Indiana University)
An analytical technique similar to the Epsilon expansion in
the theory of critical phenomena has been
recently proposed for a dilute
Fermi gas with two body interaction characterized by infinite
scattering length and zero effective range (unitary Fermi gas). A way
to check usefulness of the Epsilon expansion technique is to make
predictions for various observable quantities.
After an introduction to the Epsilon expansion technique, I will
describe some recent results:
1. effective Lagrangian for the Unitary Fermi Gas and structure of a
vortex;
2. low energy density correlation
functions and the dynamic structure factor.
