Title: Black Hole Microstates in AdS_4 From Supersymmetric Localisation
Speaker: Kiril Hristov (Inst. Nucl. Res., Sofia)
Abstract: This talk addresses the problem of counting the microstates of supersymmetric asymptotically AdS black holes in terms of a holographically dual field theory. We focus on a class of asymptotically AdS_4 static black holes preserving two real supercharges which are dual to a topologically twisted deformation of the ABJM theory. We evaluate in the large N limit the topologically twisted index of the ABJM theory and show that it correctly reproduces the entropy of the AdS_4 black holes. An extremization of the index with respect to a set of chemical potentials is required. We interpret it as the selection of the exact R-symmetry of the superconformal quantum mechanics describing the horizon of the black hole.
Time: Monday 7th November 2016, 2.30pm.
Place: Lecture Room, 1st Floor, School of Theoretical Physics, DIAS, 10 Burlington Road, Dublin 4.

This #WorldBookDay we're highlighting @ISC's scientific publishing work on a set of principles to maximize benefit to global science and wider audiences for scientific research. DIAS's own @Luke_Drury is on the steering group. 📖 council.science/actionplan/fut… #DIASdiscovers #copyright
@DIASAstronomy's @jm_astro is the proposer & co-chair of the scientific & local organising committees of this Symposium. The Virtual Preview meeting is just the start! Hopefully in May 2022, we will host an in-person meeting in Cavan in Ireland 🤞 #IAU361 #DIASdiscovers twitter.com/IAUS361/status…
"Creativity is a function of being human... " 🧪🔬💢💥💫⚫️🧮👩🔬👨🔬 This @WorldCreativity and Innovation day Check out @Luke_Drury 's paper for the @RIAdawson on Creativity in the Sciences. 👉ria.ie/sites/default/… #IAmCreative #DIASdiscovers #creativity #science #WCIW
Day two of our posts for #TechWeek2021. DIAS's Astronomy & Astrophysics section work closely with advanced technology in charting and exploring our Universe. #DIASdiscovers twitter.com/DIASAstronomy/…
The DIAS Geophysics Section are pleased to announce today's publication of: "How deep ocean-land coupling controls the generation of secondary microseism Love waves" #DIASdiscovers twitter.com/dias_geophysic…
John T Lewis also co-founded @CorvilInc, a company that focuses on the measurement and performance of internet traffic. #DIASdiscovers twitter.com/StpDias/status…
It's #TechWeek2021 and we are highlighting some of the amazing tech projects DIAS is apart of. First is the great work of our Geophysics section #DIASdiscovers #tech twitter.com/dias_geophysic…
