The Mass Gap of the Nonlinear Sigma Model through the Finite Temperature Effective Action
D. Senechal
The nonlinear model is studied in the disordered phase, using the techniques of the effective action and finite temperature field theory. The nonlinear constraint is imp…

Chern-Simons superconductivity
D. Senechal
We argue that a simple Yukawa coupling between the nonlinear $\s$-model and charged Dirac fermions leads, after one-loop quantum corrections, to a Meissner effect, in the di…
