THE PARTITION-FUNCTION FOR AN ANYON-LIKE OSCILLATOR
(Journal of Physics A: Mathematical and General, 1995-01-07) [Carta]
We compute the partition function of an anyon-like harmonic oscillator. The well known results for both the bosonic and fermionic oscillators are then re-obtained as particular cases of our function. The technique we employ ...
Ordering ambiguity versus representation
(Journal of Physics A: Mathematical and General, 2006-01-06) [Artigo]
In this work we show that the ordering ambiguity on quantization depends on the representation choice. This property is then used to solve unambiguously some particular systems. Finally, we speculate on the consequences ...
Quartic fermion self-interactions in two-dimensional gauge theories
(Physical Review D: Particles, Fields, Gravitation and Cosmology, 1997-04-15) [Artigo]
In this work we discuss the effect of quartic fermion self-interacting terms on the dynamically generated photon masses in 1+1 dimensions, for vector, chiral, and non-Abelian couplings. In the vector and chiral cases we ...
BRST-BFV formalism for the generalized Schwinger model
(Zeitschrift fur Physik C: Particles and Fields, 1997-07-01) [Artigo]
We derive the Wess-Zumino scalar term of the generalized Schwinger model both in the singular and nonsingular cases by using BRST-BFV framework. The photon propagators are also computed in the extended Lorentz gauge.
New possibilities for the gauging of chiral bosons
(Physical Review D, 2003-02-15) [Artigo]
We study a new mechanism for the electromagnetic gauging of chiral bosons showing that new possibilities emerge for the interacting theory of chiral scalars. We introduce a chirally coupled gauge field necessary to mod out ...
COMPARISON OF THE ANOMALOUS AND NONANOMALOUS GENERALIZED SCHWINGER MODELS VIA THE FUNCTIONAL FORMALISM
(International Journal of Modern Physics A, 1994-05-20) [Artigo]
We calculate the Green functions of the two versions of the generalized Schwinger model, the anomalous and the nonanomalous one, in their higher order Lagrangian density form. Furthermore, it is shown through a sequence ...
Generalizing the soldering procedure
(Physical Review D, 2006-07-01) [Artigo]
We start this work by revisiting the problem of the soldering of two chiral Schwinger models of opposite chiralities. We verify that, different from what one can conclude from the current literature, the usual sum of these ...
Approximate expression for the energy of a D-dimensional anharmonic oscillator
(Journal of Physics A: Mathematical and General, 2003-02-14) [Artigo]
An approximate expression is constructed for the energy of an anharmonic potential with centrifugal barrier. In order to obtain such an analytical expression, the quasi-exact solvability is used and then a fitting of these ...
On the quantum mechanical propagator for driven coupled harmonic oscillators
(Journal of Physics A: Mathematical and General, 1992-08-07) [Artigo]
The exact propagator beyond and at caustics for a pair of coupled and driven oscillators with different frequencies and masses is calculated using the path-integral approach. The exact wavefunctions and energies are also ...
CHIRAL SCHWINGER MODEL WITH A PODOLSKY TERM AT FINITE-TEMPERATURE
(Zeitschrift fur Physik C: Particles and Fields, 1995-08-01) [Artigo]
We study an exactly solvable two-dimensional model which mimics the basic features of the standard model. This model combines chiral coupling with an infrared behavior which resembles low energy QCD. This is done by adding ...
