Extended Thermodynamics and Renyi Entropy Beyond Fixed Central Charge
Chatchai Promsiri, Phuwadon Chunaksorn, Ratchaphat Nakarachinda +1
An outstanding problem in the framework of conformal thermodynamics concerns the interpretation of variations in the central charge . In this paper, we construct a novel central…
Integral Transformations for Conformally Invariant Celestial Amplitudes
Aphiwat Yuenyong, Pongwit Srisangyingcharoen, Ekapong Hirunsirisawat +1
We propose an integral transformation for celestial gluon amplitudes that maps the celestial coordinates \((z_i,\bar z_i)\) to a new set of complex variables \((s_i,\bar s_i)\), in…
Observing Black Hole Phase Transitions in Extended Phase Space and Holographic Thermodynamics Approaches from Optical Features
Chatchai Promsiri, Weerawit Horinouchi, Ekapong Hirunsirisawat
The phase transitions of charged Anti-de Sitter (AdS) black holes are characterized by studying null geodesics in the vicinity of the critical curve of photon trajectories around b…
