Abstract:
In this talk, I will review the framework of black hole thermodynamics set up by Bekenstein & Hawking in the 70's, and possible insights it could shed on quantum theories of gravity. I will then describe the low temperature (high-spin) limit of thermodynamics of rotating black holes, and I will review an old puzzle related to the breakdown of thermodynamics as the black hole spins close to the speed of light. Then, I will discuss recent work in which we resolved this puzzle by properly accounting for quantum corrections which dominate the low-temperature thermodynamics.
Biography:
Ahmed Sheta is a PhD student at Harvard University. Originally from Egypt, he did his bachelor's at Columbia University (Class of 2021) and is currently a graduate student in the group of Andrew Strominger. He is working on various aspects of black hole physics, within both classical and quantum gravity.
NOTE: All PHY Graduate Students are ENCOURAGED to attend. All interested parties are invited to attend. Open to the public.
