In the AdS/CFT context\, they\nhave been also shown to provide great insights into the comprehension of\nthe entropy area law and in the black hole information problem. For a\nCFT with a global symmetry\, it is possible to extend the notion to the\nso called “charged Renyi entropy” by means of a conformal map that leads\nto a grand canonical partition function with a Wilson loop encircling\nthe entangling region. This quantity has been conjectured to be\nholographically dual to charged black holes. In this talk we extend this\nresult to include nonlinear sources and compute the thermal fluctuations\non the gravity side. These corrections lead to a new logarithmic\ndivergence in the entanglement entropy which usually appear in a field\ntheory with spontaneous breaking of a continuous symmetry.” \n  \n\nAnthony Osses (UC): “Breve introducción a las amplitudes celestiales:\nel plano complejo de los pesos conformes”\n\nAbstract: “En esta charla se dará una breve introducción a “Amplitudes\ncelestiales”. Estas son una realización de holografia en espacios\nasintoticamente planos que mapea amplitudes de scattering en 4D\nfunciones a funciones de correlación de una aún desconocida 2D CFT. Se\ndará especial énfasis al rol que juega la estructura analítica de los\npesos conformes y cómo ésta conecta el IR y el UV de una nueva e\ninteresante manera.” \n[/vc_column_text][/vc_column][/vc_row] URL:https://holography.cl/activity/journal-club/ LOCATION:Online\, Zoom CATEGORIES:Journal Club END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Santiago:20221014T130000 DTEND;TZID=America/Santiago:20221014T143000 DTSTAMP:20260505T173948 CREATED:20221013T162939Z LAST-MODIFIED:20230524T032129Z UID:4028-1665752400-1665757800@holography.cl SUMMARY:Max Metlitski MIT DESCRIPTION:[vc_row][vc_column][vc_column_text css=”.vc_custom_1665623294973{margin-top: 20px !important;margin-bottom: 40px !important;}”] \nHolographyCL Seminar on October 14\nWe are happy to announce a special seminar!

Understanding one-dimensional conformal symmetry is essential in such a scenario. This time we will discuss the expression Σ=sgn(τ1-τ2)+sgn(τ2-τ3)+sgn(τ3-τ4)+sgn(τ4-τ1) which arises in the context of calculating a 4-point function applying the GKPW prescription to a propagating scalar field in AdS2 with interpolating boundary conditions between Dirichlet and Neumann. The fact that Σ is conformally invariant and cannot be written as a function of the invariant u (cross ratio) challenges us to ask ourselves questions to reflect on. \n  \n\nRodrigo Olea (UNAB): “On minimal surfaces”\n\nAbstract: We explore the connection between the notion of minimality\nfor surfaces in manifolds with conical defects and what is usually computed from Variational Calculus. In addition\, in a holographic framework\, we renormalize the codimension-2 area functional for surfaces anchored to the conformal boundary. \n[/vc_column_text][/vc_column][/vc_row] URL:https://holography.cl/activity/journal-club-2/ LOCATION:Online\, Zoom CATEGORIES:Journal Club END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Santiago:20220608T140000 DTEND;TZID=America/Santiago:20220608T153000 DTSTAMP:20260505T173948 CREATED:20220608T180021Z LAST-MODIFIED:20230524T031314Z UID:4319-1654696800-1654702200@holography.cl SUMMARY:Pedro Vieira ICTP-SAIFR/Perimeter Institute DESCRIPTION:HolographyCL Seminar on June 08\n\n\n\nWe announce our next seminar to be held on June 08 where Prof. Pedro Vieira from the Perimeter Institute for Theoretical Physics and the South American Institute for Fundamental Research (ICTP – SAIFR) will present his talk entitled “Stampedes: Exactly Solvable Corners of QFTs”. \n\n\n\n📖Abstract \n\n\n\n  \n\n\n\n📍The seminar will be via Zoom \n\n\n\n🔖 Registration \n\n\n\nTo register for this seminar please send an email to contacto@holography.cl with your full name and RUT (ID number).

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.
