Recently a formulation of overlap fermions at finite density based on an analytic continuation of the sign function was proposed. We analyze this proposal by computing the free energy density and number operator as a function of the chemical potential and the temperature . Our results show that overlap fermions with chemical potential reproduce the correct continuum behaviour.
