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…
Thermodynamic Stability of Schwarzschild-de Sitter Black holes with Rényi entropy
Thanawat Anusonthi, Pitayuth Wongjun, Ratchaphat Nakarachinda
Even though, classically, a black holes is gravitational object, it can be treated as a thermodynamic object when quantum effect is taken into account. It is found that by using Gi…
Greybody Factor for massive scalar field in charged black hole
Ratchaphat Nakarachinda, Suppawit Polkong, Pitayuth Wongjun
The greybody factor of a massive scalar field in the Reissner-Nordström black hole is investigated using the Wentzel-Kramers-Brillouin (WKB) approximation and rigorous bound method…
