Renormalization group analysis of phase transitions in the two dimensional Majorana-Hubbard model

Event Information:

A lattice of interacting Majorana modes can occur in a superconducting film on a topological insulator in a magnetic field. The phase diagram as a function of interaction strength for the square lattice was analyzed recently using a combination of mean field theory and field theory and was found to include second order phase transitions. One of these corresponds to sponta- neous breaking of an emergent U(1) symmetry, for attractive interactions.
