Title: DYNAMICAL VIOLATION OF SCALE INVARIANCE AND THE DILATON IN A COLD FERMI GAS

Abstract: 

There has been some interest in approximately scale invariant relativistic quantum field theories where the scale symmetry can be spontaneously broken, resulting in the appearance of a light dilaton as a pseudo-Goldstone boson. I will discuss the possible realization in the scenario sd an exotic phase of a cold, two-dimensional, multicomponent Fermi gas.
