Quantum Field Lagrangian model for charge density waves in one-dimensional systems at finite temperature : A Thermofield Dynamics Approach
Luiz Victorio Belvedere, Rubens Gurgel Amaral, Armando Flavio Rodrigues
We consider the Thermofield Dynamics bosonization to perform a field theory analysis of the effective Lagrangian model for incommensurate charge density waves (ICDW) in one-dimensi…
Thermofield Quantum Electrodynamics in 1 + 1 Dimensions at Finite Chemical Potential: A Bosonization Approach
R. L. P. G. Amaral, L. V. Belvedere, K. D. Rothe
The recent generalization of the Lowenstein-Swieca operator solution of Quantum Electrodynamics in 1+1 dimensions to finite temperature in Thermofield Dynamics is further generaliz…
Two-Dimensional Thermofield Bosonization II: Massive Fermions
R. L. P. G. Amaral, L. V. Belvedere, K. D. Rothe
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 in…
Bosonized Quantum Hamiltonian of the Two-Dimensional Derivative-Coupling Model
L. V. Belvedere, A. F. Rodrigues
Using the operator formulation we discuss the bosonization of the two-dimensional derivative-coupling model. The fully bosonized quantum Hamiltonian is obtained by computing the co…
The Thirring interaction in the two-dimensional axial-current-pseudoscalar derivative coupling model
L. V. Belvedere, A. F. Rodrigues
The authors reexamine the two-dimensional model of massive fermions interacting with a massless pseudoscalar field via axial-current-pseudoscalar derivative coupling. Performing a…
Two-Dimensional Thermofield Bosonization
R. L. P. G. Amaral, L. V. Belvedere, K. D. Rothe
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 t…
