SUMMARY:Polygonal Gravity Seminars
DESCRIPTION:Madrid’s Polygonal Gravity Seminar Series\nWednesday\, September 30th. Red Room (IFT)\n  \n11:15h Welcome coffee \n————————- \n11:30h First talk \nSpeaker: Sameer Murthy (Kingś College\, London) \nTitle: Near-extremal black holes in GR and in string theory \nAbstract:What happens to the thermodynamics of a black hole at very low temperatures as it\napproaches extremality? This question had remained a puzzle for many decades. Recent progress shows\nthat semi-classical physics in the near-extremal limit needs to be revisited due to the appearance\nof nearly gapless modes in the near-horizon of a near-extremal black hole. Upon approaching the\nextremal limit carefully\, one finds that the quantum fluctuations of these gapless modes leads to\nunexpectedly large effects even for a very massive black holes with weakly-curved horizons. In the\nfirst part of this talk\, I will explain this progress and discuss various applications. \nIn the second half of the talk\, I will discuss progress regarding the calculation of entropy of\nsupersymmetric black holes\, which has been one of the big successes of string theory. I will discuss\nhow the counting of entropy in string theory involves a subtlety regarding the supersymmetric index\,\nand how its resolution also involves\, once again\, taking the extremal limit carefully. Finally\, I\nwill discuss how this procedure leads to a new class of supersymmetric solutions corresponding to\nblack holes and black strings. \n————————- \n12:45-14:45 Lunch break and free time \n————————- \n15:00h Second talk \nSpeaker: Luciano Rezzolla (Institute of Theoretical Physics\, Goethe U.\, Frankfurt) \nTitle: Binary Neutron Stars: from macroscopic collisions to microphysics  \nAbstract: I will argue that if black holes represent one the most fascinating implications of\nEinstein’s theory of gravity\, neutron stars in binary system are its richest laboratory\, where\ngravity blends with astrophysics and particle physics. I will discuss the rapid recent progress made\nin modelling these systems and show how the gravitational signal can provide tight constraints on\nthe equation of state and sound speed for matter at nuclear densities\, as well as on one of the most\nimportant consequences of general relativity for compact stars: the existence of a maximum mass.\nFinally\, I will discuss how the merger may lead to a phase transition from hadronic to quark matter.\nSuch a process would lead to a signature in the post-merger gravitational-wave signal and open an\nobservational window on the production of quark matter in the present Universe. \n———————————————– \n16:00h Coffee time \n———————————————– \nMore information about these and following monthly seminars can be found at the  webpage https://sites.google.com/view/polygrav (No registration is needed)
