Star-UBB Seminar Series:- Hidden conformal symmetry for dyonic Kerr-Sen black hole and its gauged family

In this talk, the speaker and his team explore the conformal invariance of the dyonic Kerr-Sen black hole and its gauged family. They consider a neutral massless scalar probe on the black holes’ background within the low-frequency limit and exhibit that the solution space possesses SL(2,R)×SL(2,R) isometry. They then successfully derive the Bekenstein-Hawking entropy using Cardy entropy formula from 2D Conformal Field Theory(CFT). Furthermore, they also calculate the absorption cross-section from gravity side for generic non-extremal dyonic Kerr-Sen black hole and near-extremal gauged dyonic Kerr-Sen black hole. Their calculations show that those quantities are in a perfect match with the calculation from CFT. Their findings further support the duality between rotating black holes and CFTs.

Scientific and Technological Advanced Research- Babeș-Bolyai University(Star-UBB) Seminar Series in Gravitation, Cosmology and Astrophysics

Presently a period of rapid and intense change are being witnessed in our understanding of the gravitational force, at a rate that is quickly increasing since the important observational discoveries of the late 1990s. With the advent of new observational techniques, the emergence of important cosmological and astrophysical paradigms can be seen that lead to a deep change in our understanding of the Universe. Astronomical observations strongly suggest that at large scales the force of gravity may not behave according to standard general relativity, and that a generalization of the gravitational action, either at the geometric level, or at the matter level, may be required for a full understanding of the gravitational interaction.

The goal of the present seminar is to bring Theoretical Gravitational Physics closer to the observations and experiments, and to discuss current topics in general relativity, high-energy physics, astrophysics and cosmology.
