Variational Calculations for the Relativistic Interacting Fermion System at Finite Temperature: Application to Liquid 3He
In this paper, at first we have formulated the lowest order constrained variational method for the relativistic case of an interacting fermion system at finite temperature. Then we have used this formalism to calculate some thermodynamic properties of liquid in the relativistic regime. The results show that the difference between total energies of relativistic and non-relativistic cases of liqu...
متن کاملSome remarks on the Ginsparg-Wilson fermion
We note that Fujikawa’s proposal of generalization of the GinspargWilson relation is equivalent to setting R = (aγ5D) 2k in the original Ginsparg-Wilson relation Dγ5 + γ5D = 2aDRγ5D. An explicit realization of D follows from the Overlap construction. The general properties of D are derived. The chiral properties of these higher-order ( k > 0 ) realizations of Overlap Dirac operator are compared...

متن کاملUniversal dephasing in a chiral 1D interacting fermion system.
We consider dephasing by interactions in a one-dimensional chiral fermion system (e.g., a quantum Hall edge state). For finite-range interactions, we calculate the spatial decay of the Green's function at fixed energy, which sets the contrast in a Mach-Zehnder interferometer. Using a physically transparent semiclassical ansatz, we find a power-law decay of the coherence at high energies and zer...
متن کاملRemarks on Interacting Neimark-Sacker Bifurcations
We study codimension-2 bifurcations of fixed points of dissipative diffeomorphisms with a pair of complex critical eigenvalues together with either an eigenvalue −1 or another such a pair. In the previous studies only cubic normal forms were considered. However, in some cases the unfolding requires higher order terms and these are investigated here. We (re)derive the normal forms and reduce the...
