Wick Rotation and Abelian Bosonization
Aleksandar Bogojevic, Olivera Miskovic
We investigate the connection between Abelian bosonization in the Minkowski and Euclidean formalisms. The relation is best seen in the complex time formalism of S. A. Fulling and S…
Abelian Bosonization, the Wess-Zumino Functional and Conformal Symmetry
A. Bogojevic, B. Sazdovic, O. Miskovic
We look at the equivalence of the massive Thirring and sine-Gordon models. Previously, this equivalence was derived perturbatively in mass (though to all orders). Our calculation g…
Improved Gaussian Approximation
Antun Balaz, Aleksandar Belic, Aleksandar Bogojevic
In a recently developed approximation technique for quantum field theory the standard one-loop result is used as a seed for a recursive formula that gives a sequence of improved Ga…
The Measure from Schwinger-Dyson Equations
Aleksandar Bogojevic, Dragan S. Popovic
We review a new prescription for calculating the Lagrangian path integral measure directly from the Hamiltonian Schwinger-Dyson equations. The method agrees with the usual way of d…
The Role of Conformal Symmetry in Abelian Bosonization of the Massive Thirring Model
Aleksandar Bogojevic, Branislav Sazdovic, Olivera Miskovic
We show equivalence between the massive Thirring model and the sine-Gordon theory by gauge fixing a wider gauge invariant theory in two different ways. The exact derivation of the…
An Improved Gaussian Approximation for Quantum Field Theory
Antun Balaz, Aleksandar Belic, Aleksandar Bogojevic
We present a new approximation technique for quantum field theory. The standard one-loop result is used as a seed for a recursive formula that gives a sequence of improved Gaussian…
