(cid:127) Preface This book is based upon lectures held from 29 June to 3 July 2009 at the INFN-Laboratori Nazionali di Frascati School on Attractor Mechanism, directed by Stefano Bellucci, with the participation of prestigious lecturers, including M. Cvetic, G. DallAgata, S. Ferrara, J.F. Morales, G. Moore, A. Sen, J. Simon, andM.Trigiante,aswellasinvitedscientistsofthecaliberofM.Bianchi,C.Nappi, A. Sagnotti, and E. Witten. All lectures were given at a pedagogical,introductory level, a feature which reflects itself in the specific “flavor” of this volume, which alsobenefitedmuchfromextensivediscussionsandrelatedreworkingofthevarious contributions. This is the fifth volume in a series of books on the general topics of supersymmetry, supergravity, black holes, and the attractor mechanism.

TheexistenceofblackholesseemstobeanunavoidableconsequenceofGeneral Relativity (GR) and of its extensions (like supergravity). Classically, the horizon of black holes protects the physics in the outer region from what happens in the vicinity of singular field configurations that can arise in GR from smooth initial data. However, already at the semiclassical level, black holes emit particles with a thermalspectrum[7,58]. A thermodynamicbehaviourcan also be associated to blackholesfromthelawsgoverningtheirmechanics[79]and,inparticular,onecan associatetoablackholeanentropyS proportionaltotheareaAofitseventhorizon (measuredinPlanckunitsl2 DG„=c3) P k A B S D : (1.1) l2 4 P In most physical systems the thermodynamicentropy has a statistical interpre- tationintermsofcountingmicroscopicconfigurationswiththesamemacroscopic G.Dall’Agata((cid:2)) DipartimentodiFisica“GalileoGalilei”,Universita`diPadova,ViaMarzolo8,35131, Padova,Italy INFN,SefionediPadova,ViaMarzolo8,35131,Padova,Italy e-mail:[email protected] S.Bellucci(ed.),SupersymmetricGravityandBlackHoles,SpringerProceedings 1 inPhysics142,DOI10.1007/978-3-642-31380-6 1, ©Springer-VerlagBerlinHeidelberg2013
