Dynamical symmetries in noncommutative theories
Ricardo Amorim
In the present work we study dynamical space-time symmetries in noncommutative relativistic theories by using the minimal canonical extension of the Doplicher, Fredenhagen and Robe…
Tensor Operators in Noncommutative Quantum Mechanics
Ricardo Amorim
Some consequences of promoting the object of noncommutativity to an operator in Hilbert space are explored. Consequently, a consistent algebra involving the enla…
Partially embedding of the quantum mechanical analog of the nonlinear sigma model
R. Amorim, J. Barcelos-Neto, C. Wotzasek
We consider the quantum mechanical analog of the nonlinear sigma model. There are difficulties to completely embed this theory by directly using the Batalin, Fradkin, Fradkina, and…
Extended supersymmetry in D=1+1
R. Amorim, J. Barcelos-Neto
We extend superspace by introducing an antisymmetric tensorial coordinate. The resulting theory presents a supersymmetry with central charge. After integrating over the tensorial c…
Field-antifield formalism in a non-Abelian theory with one and two form gauge fields coupled in a topological way
R. Amorim, J. Barcelos-Neto
We make a systematic development of the non-Abelian formulation of two-form gauge fields with topological coupling with the Yang-Mills one-form connection. An analysis of the gauge…
Axial and gauge anomalies in the field antifield quantization of the generalized Schwinger model
R. Amorim, N. R. F. Braga, R. Thibes
In the generalized Schwinger model the vector and axial vector currents are linearly coupled, with arbitrary coefficients, to the gauge connection. Therefore it represents an inter…
