Multivalued Entropy of Supersymmetric Black Holes
Renata Kallosh
The supersymmetric flow equations describing the flow of moduli from infinity to the black hole horizon, and vice versa, are derived in the five-dimensional theories where the modu…
Supersymmetric Multiple Basin Attractors
Renata Kallosh, Andrei Linde, Marina Shmakova
We explain that supersymmetric attractors in general have several critical points due to the algebraic nature of the stabilization equations. We show that the critical values of th…
Gravitino Production After Inflation
Renata Kallosh, Lev Kofman, Andrei Linde +1
We investigate the production of gravitinos in a cosmological background. Gravitinos can be produced during preheating after inflation due to a combined effect of interactions with…
BRST Quantization of a Particle in AdS_5
Piet Claus, Renata Kallosh, J. Rahmfeld
We perform the quantization of a massive particle propagating on AdS_5. We use the twistor formulation in which the action can be brought into a quadratic form. We construct the BR…
Supertwistors as Quarks of SU(2,2|4)
Piet Claus, Murat Gunaydin, Renata Kallosh +2
The GS superstring on AdS_5 x S^5 has a nonlinearly realized, spontaneously broken SU(2,2|4) symmetry. Here we introduce a two-dimensional model in which the unbroken SU(2,2|4) sym…
Black Holes, Branes and Superconformal Symmetry
Renata Kallosh
The main focus of this lecture is on extended objects in adS*S bosonic backgrounds with unbroken supersymmetry. The backgrounds are argued to be exact, special consideration are gi…
