Inflation from Covariant Signature Change: A Geometric Mechanism
Raghvendra Singh, Sergey Bondarenko
We present a covariant mechanism in which a smooth change of metric signature, from a Euclidean to a Lorentzian regime, drives a finite interval of accelerated expansion. The trans…
Modeling an internal structure of a black hole using a thermodynamic quasi-particle model
Sergey Bondarenko, Dima Cheskis, Raghvendra Singh
We develop an effective thermodynamic model for a black-hole interior composed of scalar quasiparticles. The interior is represented by two regions: a dense core and a surrounding…
A realistic photon spectra in polarized γγ processes in SANCphot
Sergey G. Bondarenko, Aidos Issadykov, Lidia V. Kalinovskaya +1
This work presents an approach to improve the precision of polarized photon-photon collisions simulation implemented in the SANCphot package. The basic linear Compton approximation…
