Noncommutative Particles in Curved Spaces
E. M. C. Abreu, R. Amorim, W. Guzmán Ramírez
We present a formulation in a curved background of noncommutative mechanics, where the object of noncommutativity is considered as an independent quantity having a canonic…
Noncommutative relativistic particles
R. Amorim, E. M. C. Abreu, W. G. Ramirez
We present a relativistic formulation of noncommutative mechanics were the object of noncommutativity is considered as an independent quantity. Its canonical conjugate mom…
Quantum complex scalar fields and noncommutativity
Ricardo Amorim, Everton M. C. Abreu
In this work we analyze complex scalar fields using a new framework where the object of noncommutativity represents independent degrees of freedom. In a first quantized fo…
Fermions and noncommutative theories
Ricardo Amorim
By using a framework where the object of noncommutativity represents independent degrees of freedom, we study the symmetry properties of an extended space-time, give…
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 Coordinates in Noncommutative Mechanics
Ricardo Amorim
A consistent classical mechanics formulation is presented in such a way that, under quantization, it gives a noncommutative quantum theory with interesting new features. The Dirac…
