Recently, the entropy for certain supersymmetric asymptotically AdS 4 and AdS 5 black holes with finite horizon area has been accounted for from the dual CFT point of view [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31].

We construct the microstates of near-extremal black holes in AdS5 Ã S5 as gases of defects distributed in heavy BPS operators in the dual SU(N) Yang-Mills theory. Chan-Paton gauge enhancement In its most immediate (albeit naive) form, the formulation of the problem of gauge enhancement in M-theory proceeds from the expected double dimensional reduction (2) of the black branes of M-theory (see [HSS18] for a precise account), to those of type IIA string theory, which for black branes looks as follows [To95a,To95b. We exhibit a novel kind of phase transition between these cosmological spacetimes and the Minkowski vacuum. This gives rise to an ordinary 1+1 field theory above some...

We investigate the first law of complexity proposed in Bernamonti et al (2019 Phys. We determine the moduli space of smooth (supersymmetric) Kaluza-Klein reductions by classifying the freely-acting spacelike Killing vectors which preserve some Killing spinor.

BPS-saturation. School of Mathematics - Personal Chair of Geometry, Dean of Postgraduate Research; Person: Academic: Research Active , Academic: Research Active (Teaching) The holographic relation between quantum correlations and connectivity of spacetime is explored for single R-charged AdS5 black holes and their half-BPS limits (superstars).
