Perturbations and stability of black holes with static scalar hair in general GLPV theories
Petarpa Boonserm, Antonio De Felice, Ratchaphat Nakarachinda +2
We derive the background equations and complete odd- and even-parity quadratic actions for static, spherically symmetric black holes with radial scalar hair in general quartic-quin…
Black Hole Thermodynamics via Tsallis Statistical Mechanics and Phase Transitions Probed by Optical Characteristics
Phuwadon Chunaksorn, Ratchaphat Nakarachinda, Pitayuth Wongjun
We develop a non-extensive thermodynamic framework for Reissner--Nordström black holes based on a near-horizon photon-gas model within Tsallis statistics. We derive the generalized…
Schwarzschild-de Sitter black hole as a correlated qubit system via entropic identification
Ratchaphat Nakarachinda, Lunchakorn Tannukij, Pitayuth Wongjun +1
The thermodynamic behaviours of multi-horizon black holes such as a Schwarzschild-de Sitter black hole have been one of the long-standing mysteries in gravitational physics since t…
Restoration of the Lorentz symmetry of particle propagator in the ghost condensate model
Suppanat Supanyo, Pitayuth Wongjun, Lunchakorn Tannukij
The ghost condensate model has been proposed to protect the vacuum state of the cosmological phantom model yielding the gradient instability regime and the spontaneous Lorentz symm…
Greybody factors of charged black holes with axion hair
Ratchaphat Nakarachinda, Petarpa Boonserm, Antonio De Felice +2
We study the greybody factor of charged hairy black holes (BHs) that arise due to the presence of an axion coupled to the electromagnetic field. Specifically, we consider spin-0 an…
Black Hole Thermodynamics via Tsallis Statistical Mechanics
Phuwadon Chunaksorn, Ratchaphat Nakarachinda, Pitayuth Wongjun
An investigation of black hole thermodynamics based on Tsallis statistical mechanics is explored through the study of the thermodynamics of a gas system located near the horizon of…
