FADDEEV-JACKIW QUANTIZATION AND CONSTRAINTS
In a recent Letter, Faddeev and Jackiw have shown that the reduction of constrained systems into its canonical, first-order form, can bring some new insight into the research of this field. ForExpand

Dual equivalence between self-dual and Maxwell–Chern–Simons models coupled to dynamical U(1) charged matter
Abstract We study the equivalence between the self-dual and the Maxwell–Chern–Simons (MCS) models coupled to dynamical, U(1) charged matter, both fermionic and bosonic. This is done through anExpand

Duality equivalence between self-dual and topologically massive non-abelian models
Abstract The non-abelian version of the self-dual model proposed by Townsend, Pilch and van Nieuwenhuizen presents some well known difficulties not found in the abelian case, such as well definedExpand

On the hidden U(1) gauge symmetry in the nonlinear sigma model
As shown by Kovner and Rosenstein, the O(N) invariant nonlinear sigma model, which in Dirac’s language of constrained systems presents only second‐class type of constraints, possess a hidden U(1)Expand

Stuckelberg field shifting quantization of free particle on D-dimensional sphere
In this paper we quantize a free particle on a D-dimensional sphere in an unambiguous way by converting the second-class constraint using the Stuckelberg field-shifting formalism. Furthermore, weExpand

Domain walls in three-field models
We investigate the presence of domain walls in models described by three real scalar fields. We search for stable defect structures which minimize the energy of the static field configurations. WeExpand

Soldering Formalism: Theory and Applications
The soldering mechanism is a new technique to work with distinct manifestations of dualities that incorporates interference effects, leading to new physical results that includes quantumExpand

Faddeev-Jackiw approach to hidden symmetries
Abstract The study of hidden symmetries within Dirac′s formalism does not possess a systematic procedure due to the lack of first-class constraints to act as symmetry generators. On the other hand,Expand

Coupling Chiral Bosons to Gravity
The chiral boson actions of Floreanini and Jackiw (FJ), and of McClain, Wu and Yu (MWY) have recently been shown to be different representations of the same chiral boson theory. MWY displays manifestExpand

Lorentz-violating Chern–Simons action under high temperature in massless QED
Lorentz and CPT violating QED with massless fermions at finite temperature is studied. We show that there is no ambiguity in the induced coefficient of the Chern–Simons-like term that defines theExpand
