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…
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…
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…
From the BRST invariant Hamiltonian to the Field-Antifield Formalism
Heinz J. Rothe, Klaus D. Rothe
We study the relation between the lagrangian field-antifield formalism and the BRST invariant phase space formulation of gauge theories. Starting from the Batalin-Fradkin-Vilkovisk…
Gauge Identities and the Dirac Conjecture
Heinz J. Rothe, Klaus D. Rothe
The gauge symmetries of a general dynamical system can be systematically obtained following either a Hamiltonean or a Lagrangean approach. In the former case, these symmetries are…
On the Hamilton-Jacobi equation for second class constrained systems
K D Rothe, F G Scholtz
We discuss a general procedure for arriving at the Hamilton-Jacobi equation of second-class constrained systems, and illustrate it in terms of a number of examples by explicitely o…
