Open string with a background B-field as the first order mechanics and noncommutativity
A. A. Deriglazov, C. Neves, W. Oliveira
To study noncommutativity properties of the open string with constant B-field we construct a mechanical action which reproduces classical dynamics of the string sector under consid…
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…
Turbulence as a constrained system
A. C. R. Mendes, W. Oliveira, F. I. Takakura
Hydrodynamic turbulence is studied as a constrained system from the point of view of metafluid dynamics. We present a Lagrangian description for this new theory of turbulence inspi…
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:…
