We study a phase transition in a non-equilibrium model first introduced in [5], using the Yang-Lee description of equilibrium phase transitions in terms of both canonical and grand canonical partition function zeros. The model consists of two different classes of particles hopping in opposite directions on a ring. On the complex plane of the diffusion rate we find two regions of analyticity for...

Abstract We present a calculation of the grand canonical partition function serial metallic island system by imaginary-time path integral formalism. To this purpose, all electronic excitations in lead and electrodes are described using Grassmann numbers. The Coulomb charging energy is represented terms phase fields conjugate to charges. By large channel approximation, tunneling action dependenc...

We review the overlap pathology of the Glasgow reweighting method for finite density QCD, and discuss the sampling bias that effects the determination of the ensemble-averaged fugacity polynomial expansion coefficients that form the Grand Canonical Partition function. The expectation of the difference in free energies between canonical partition functions generated with different measures is pr...
