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…
Quantum Electrodynamics in Two-Dimensions at Finite Temperature. Thermofield Bosonization Approach
L. V. Belvedere, R. L. P. G. Amaral, K. D. Rothe +1
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 fin…
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…
The Thirring-Wess Model Revisited: A Functional Integral Approach
L. V. Belvedere, A. F. Rodrigues
We consider the Wess-Zumino-Witten theory to obtain the functional integral bosonization of the Thirring-Wess model with an arbitrary regularization parameter. Proceeding a systema…
