Snyder and their representation with creation and annihilation operators
Juan M. Romero, Leonardo Ortíz
Inspired by the Schwinger's representation of angular momentum, we propose a representation of certain operators where we use the algebra of the annihilation and creation operators…
Aspects of the BTZ black hole interacting with fields
Leonardo Ortíz, Nora Bretón
We show that there is no superradiance for the Dirac field in the rotating BTZ black hole if the field vanishes at infinity. Then we outline the calculation of the expression for t…
On a Boltzmann equation for Compton scattering, from non relativistic electrons at low density
E. Cortés, M. Escobedo
A Boltzmann equation, used to describe the evolution of the density function of a gas of photons interacting by Compton scattering with electrons at low density and non relativisti…
Notes on quantum fields on two dimensional spacetimes
Leonardo Ortíz
We point out how to construct the Hartle-Hawking-Israel state for the minimaly coupled massless quantum real scalar field in the two dimensional BTZ black hole. We also calculate t…
Non-Paradoxical Loss of Information in Black Hole Evaporation in a Quantum Collapse Model
Sujoy K. Modak, Leonardo Ortíz, Igor Peña +1
We consider a novel approach to address the black hole information paradox (BHIP). The idea is based on adapting, to the situation at hand, the modified versions of quantum theory…
A note on the two point function on the boundary of AdS spacetime
L. Ortíz
We calculate by a new way the two point function on the boundary of AdS spacetime in 1+2 dimensions for the massless conformal real scalar field. The result agrees with the answer…
No superradiance for the scalar field in the BTZ black hole with reflexive boundary conditions
L. Ortíz
We show that there is no superradiance in the rotating BTZ black hole for vanishing boundary conditions at infinity for the real scalar field
Thermal state on a cylindrical spacetime
L. Ortíz
We proof that if we have a thermal equilibrium state on Minkowski spacetime in two dimensions then we have a thermal equilibrium state on the cylindrical spacetime obtained from th…
