Shadow cast of non-commutative black holes in Rastall gravity
Ali Övgün, İzzet Sakallı, Joel Saavedra +1
We study the shadow and energy emission rate of a spherically symmetric non-commutative black hole in Rastall gravity. Depending on the model parameters, the non-commutative black…
Generalized commutation relations and Non linear momenta theories, a close relationship
Hector Calisto, Carlos Leiva
A revision of generalized commutation relations is performed, besides a description of Non linear momenta realization included in some DSR theories. It is shown that these proposit…
Extended Non Linear Conformal Symmetry and DSR Velocities on the Physical Surface
Carlos Leiva
The relation between Conformal generators and Magueijo Smolin Deformed Special Relativity term, added to Lorentz boosts, is achieved. The same is performed for Fock Lorentz transfo…
Nonlinear superconformal symmetry of a fermion in the field of a Dirac monopole
Carlos Leiva, Mikhail S. Plyushchay
We study a longstanding problem of identification of the fermion-monopole symmetries. We show that the integrals of motion of the system generate a nonlinear classical Z_2-graded P…
Superconformal mechanics and nonlinear supersymmetry
Carlos Leiva, Mikhail S. Plyushchay
We show that a simple change of the classical boson-fermion coupling constant, , , in the superconformal mechanics model gives rise to a radical change of a sy…
Conformal Symmetry of Relativistic and Nonrelativistic Systems and AdS/CFT Correspondence
Carlos Leiva, Mikhail S. Plyushchay
The nonlinear realization of conformal so(2,d) symmetry for relativistic systems and the dynamical conformal so(2,1) symmetry of nonrelativistic systems are investigated in the con…
Algebra of chiral currents on the physical surface
Alexis Amezaga, Carlos Leiva
Using a particular structure for the Lagrangian action in a one-dimensional Thirring model and performing the Dirac's procedure, we are able to obtain the algebra for chiral curren…
