  1. MI12 Supersymmetry, Black Holes and Quantum Gravity Motivation: Black holes have been one of the most intriguing physical phenomena since their earliest description in general relativity. Although first discarded by some as mere theoretical aberrations, their real physical existence is by now supported by various experimental data. There also exists an impressive analogy between the laws of Classical Thermodynamics and the laws of the Black Hole Mechanics. I. F. Mirabel, Black holes: from stars to galaxies, astro-ph/0612188; R. Genzel and V. Karas, The Galactic Center, 0704.1281; J. Kormendy, The Stellar-Dynamical Search for Supermassive Black Holes in Galactic Nuclei, astro-ph/0306353 Area of research: Supersymmetric theory of gravity Connection between the black hole entropy and topological string partition functions Connection between macroscopic and microscopic interpretations of black objects Multicenter black hole systems

  2. Current topics of research 1] The systematical construction of the first order for-malism for multi-centered black holes with flat three dimensional base-space in N = 2, D = 4 ungauged Maxwell-Einstein supergravity 2] Investigation of the "horizontal" symmetry of multi-centered soultions in supergravity theories in D=4. 3] Investigation of the "black hole / qubit correspondence", relating the mathematical structures underlying the entropy of extremal black holes with Quantum Information Theory and the entang-lement of qubits, or more generally of qubits. 4] Investigation of non-linear (triple) structures in supergravities, such as the so-called "Freudenthal duality", defined as an anti-involution on the dyonic charge vector in d = 4 space-time dimensions for Lie U-algebras "of type e7".

  3. Current topics of research 5] Analysis of the stratification structure of the space of fluxes associated to black p-branes in supergravities in any dimension, and with any amount of supersymmetry. 6] Analysis of the geometry of the scalar fields coupled to Einstein supergravity, with a maximally covariant subsequent formulation of the associated non-linear sigma model. 7] Investigation of D = 4, N >1 extended supergravities (and related compactifications of superstring theory), with particular focus on their consistent truncation to models of N = 1 supergravity, relevant for phenomenological and cosmological applications. These features of supergravity, following from the electric-magnetic duality, may be useful in other applications, like stabilization of moduli, and in studies of non-perturbative black-hole solutions of supergravity/string theory.
