Online Seminar〝Near horizon soft hair〞


Star-UBB Seminar Series:- Near horizon soft hair

Asymptotic symmetries have been crucial in understanding the holographic principle from a gravity perspective since they coincide with the global symmetries of the dual quantum field theory. A few years ago, The speaker and his team extended this notion to near horizon symmetries with some unexpected technical and conceptual insights, notably the discovery of soft Heisenberg hair. He summarizes these developments and give an outlook.

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.
