SUMMARY:Séminaire du LPTMS: Iosif Bena - LPTMS-batiment 100\, salle des co
 nseils - 9 Mai 12 11:00
DESCRIPTION:Trous noirs dans la Théorie des Cordes\nIosif Bena (IPhT Sacla
 y)\nString theory is a quantum theory of gravity\, and has had several ama
 zing successes in describing black holes. After discussing some paradoxes 
 related to the physics of black holes\, I will explain how to construct bl
 ack holes in string theory\, and how to count their entropy. I will then d
 escribe a new paradigm in the study of black holes that recent research ap
 pears to support: a black hole solution gives only a thermodynamic descrip
 tion of the physics\, and the "microscopical" statistical description of t
 he physics is given by a very large number of microstate geometries\, that
  look the same as a black hole from far away\, but do not have a horizon.
