Two-Dimensional Thermofield Bosonization
The main objective of this paper is to obtain an operator realization for the bosonization of fermions in 1 + 1 dimensions, at finite, non-zero temperature T . This is achieved in the framework of the real time formalism of Thermofield Dynamics. Formally the results parallel those of the T = 0 case. The well known two-dimensional Fermion-Boson correspondences at zero temperature are shown to ho...
متن کاملTwo-Dimensional Thermofield Bosonization II: Massive Fermions
We consider the perturbative computation of the N-point function of chiral densities of massive free fermions at finite temperature within the thermofield dynamics approach. The infinite series in the mass parameter for the N-point functions are computed in the fermionic formulation and compared with the corresponding perturbative series in the interaction parameter in the bosonized thermofield...
متن کاملTwo Dimensional Qcd and Abelian Bosonization
A bosonized action, that reproduces the structure of the ’t Hooft equation for QCD2 in the large-N limit, up to regularization dependent terms, is derived.
متن کاملQuantum Electrodynamics in Two-Dimensions at Finite Temperature Thermofield Bosonization Approach
The Schwinger model at finite temperature is analyzed using the Thermofield Dynamics formalism. The operator solution due to Lowenstein and Swieca is generalized to the case of finite temperature within the thermofield bosonization approach. The general properties of the statistical-mechanical ensemble averages of observables in the Hilbert subspace of gauge invariant thermal states are discuss...
متن کاملJacobians of chiral transformations and two - dimensional bosonization ∗
We formulate a complete path integral bosonization procedure for any fermionic theory in two dimensions. The method works equally well for massive and massless fermions, and is a generalization of an approach suggested earlier by Andrianov. The classical action of the bosons in the bosonized theory is identified with −i times the logarithm of the Jacobian of a local chiral transformation, with ...
