Few- and many-body quantum physics of p-wave interacting fermions in two dimensions

Due to the current search of Majorana fermions, the quantum physics of two-dimensional identical fermions with short-range p-wave interactions is of immediate interest. In the first part of the seminar, I will talk about the effective theory of a chiral p+ip fermionic superfluid at zero temperature. This theory naturally incorporates the parity and time reversal violating effects such as the Hall viscosity and the edge current. In the second part, I will concentrate on the few-body physics

near a p-wave resonance and introduce the super Efimov effect- a new type of few-body universality manifesting itself by a tower of three-body bound states with a double-exponential scaling.
