Embedding Second Class Systems via Symplectic Gauge-invariant Formalism
J. Ananias Neto, A. C. R. Mendes, C. Neves +2
In this paper we reformulate Abelian and non-Abelian noninvariant systems as gauge invariant theories using a new constraint conversion scheme, developed on the symplectic framewor…
Non-Abelian BFFT embedding, Schrödinger quantization and the anomaly of the O(N) nonlinear sigma model
E. M. C. Abreu, J. Ananias Neto, W. Oliveira +1
We embed the O(N) nonlinear sigma model in a non-Abelian gauge theory. As a first class system, it is quantized using two different approaches: the functional Schrödinger method an…
Operatorial quantization of Born-Infeld Skyrmions
Jorge Ananias Neto, Emanuel R. de Oliveira, Wilson Oliveira
The SU(2) collective coordinates quantization of the Born-Infeld Skyrmions Lagrangean is performed. The obtainment of the classical Hamiltonian from this special Lagrangean is made…
Does the Weyl ordering prescription lead to the correct energy levels for the quantum particle on the D-dimensional sphere ?
Jorge Ananias Neto, Wilson Oliveira
The energy eigenvalues of the quantum particle constrained in a surface of the sphere of D dimensions embedded in a space are obtained by using two different procedures:…
