Quadratic deformation of Minkowski space
D. Cervantes, R. Fioresi, M. A. Lledo +1
We present a deformation of the Minkowski space as embedded into the conformal space (in the formalism of twistors) based in the quantum versions of the corresponding kinematic gro…
On chiral quantum superspaces
D. Cervantes, R. Fioresi, M. A. Lledo
We give a quantum deformation of the chiral Minkowski superspace in 4 dimensions embedded as the big cell into the chiral conformal superspace. Both deformations are realized as qu…
Quantum twistors
D. Cervantes, R. Fioresi, M. A. Lledó +1
We compute explicitly a star product on the Minkowski space whose Poisson bracket is quadratic. This star product corresponds to a deformation of the conformal spacetime, whose big…
Remark on charge conjugation in the non relativistic limit
A. Cabo, D. B. Cervantes, H. Perez Rojas +1
We study the non relativistic limit of the charge conjugation operation in the context of the Dirac equation coupled to an electromagnetic field. The limit is well defined…
