Hidden symmetries and the universality of Hawking radiation
Ivan Pérez-Castro, Abdel Pérez-Lorenzana
Quantum tunneling of particles across a black hole (BH) horizon provides an intuitive interpretation of Hawking radiation (HR), yielding a conceptually simple derivation of the the…
On modified Hawking radiation under quantum gravity effects in the fermion sector
Ivan P-Castro, Héctor Aguilera-Trujillo, Hugo García-Compeán +1
In this letter, after briefly discussing Hawking radiation (HR) as quantum tunneling, we emphasize that special care must be taken when computing temperature corrections in the pre…
Discrete Symmetries in the Chiral Fermion Formalism
I. P-Castro, J. L. Díaz-Cruz, A. Pérez-Lorenzana
In this paper, we present a revision of the discrete symmetries (C, P, T, CP, and CPT) within an approach that treats 2-component Weyl spinors as the fundamental building blocks. I…
CPT Symmetry and Its Breaking in the Chiral Fermion Formalism
I. P-Castro, J. L. Díaz-Cruz, A. Pérez-Lorenzana
In this paper, we review the fundamental aspects of supergravity (SUGRA) and employ the chiral formalism to describe spin- fermions. Armed with this, we…
