SUMMARY:Alejandra Castro  University of Amsterdam
DESCRIPTION:[vc_row][vc_column][vc_column_text] \nHolographyCL Seminar on April 20\n\n\nWe announce our first seminar\, to be held next April 20\, in which Prof. Alejandra Castro from the University of Amsterdam will present her talk entitled “Near AdS-2 Spectroscopy”. \n\n\n📖Abstract \n \n“In this talk\, I will describe holographic properties of near AdS2 spacetimes that arise within spherically symmetric configurations of N=2 4-D supergravity\, for both gauged and ungauged theories. These theories pose a rich space of AdS2 x S2 backgrounds\, and their responses in the near-AdS2 region are not universal. I will show that the spectrum of operator dual to the matter fields\, and their cubic interactions\, are sensitive to the properties of the background and the theory it is embedded in. The properties that have the most striking effect are whether the background is BPS or non-BPS\, and if the theory is gauged or ungauged. The resulting differences will have an imprint on the quantum nature of the microstates of near-extremal black holes\, reflecting that not all extremal black holes respond equally when kicked away from extremality.” \n\n\n📍Location \n\n\nAv. República 252\, R2-413\, Campus República\, Universidad Andrés Bello \n\n\n \n\n\n🔖 Registration \n\n\nTo register for this seminar please send an email to contacto@holography.cl with your full name and RUT (ID number). You will then receive a confirmation email with a form that has to be filled in order to access to the campus. \n \n\n[/vc_column_text][/vc_column][/vc_row]
