High Energy seminars are typically held on Tuesdays and Thursdays at 16:00 p.m. either in the Euler Lecture Hall (Lower level '0') or the Luigi Stasi Seminar room (1st floor).
String seminars in Trieste is a monthly activity organized jointly by the High Energy Physics groups of ICTP and SISSA. Each event consists of two seminars given by two external speakers. The aim is to gather all theoretical physicists working in string theory and related topics in the Trieste area, and have the opportunity to get updated on what's going on in our field world-wide. The seminars take place either at ICTP or SISSA, alternately. Link to the Webpage for more information and future activities.
All seminars are announced on the High Energy board (2nd floor, near the High Energy Secretariat), on ICTP notice boards and on the ICTP Scientific Calendar.
ICTP is also happy to share information about activities hosted by its joint institute with Trieste science centres, the Institute for Fundamental Physics of the Universe (IFPU). IFPU Colloquia are seminars intended for a broad audience on topics related to the IFPU research lines. The venue for IFPU Colloquia is Lecture Hall D, in the basement of the former SISSA Main Bldg. Please check here for more information on all activities taking place at IFPU.
The mail list for our ICTP seminars is he-sem@lists.ictp.it
If you are interested in subscribing to the SISSA mailing lists, you should follow the instructions on the high-energy mailing list seminars or all the mailing lists.

Abstract. Cosmological first-order phase transitions are said to be strongly supercooled when the nucleation temperature is much smaller than the critical temperature. They are typical of potentials which feature nearly scale-invariance, for which the bounce action decreases only logarithmically with time. The phase transition takes place slowly and the probability distribution of bubble nucleation time is maximally spread. Hubble patches which get percolated later than the average are hotter than the background after reheating and potentially collapse into black holes. We discuss the formation of primordial black holes by supercooled first-order phase transitions and we present a class of particle physics models predicting such transitions.

Abstract. I will discuss how the dynamical evaporation of a black hole through quantum Hawking emission admits a dual description in terms of classical gravitational evolution in Anti-de Sitter space. The idea was first proposed two decades ago, but it remained underdeveloped and poorly understood due to conceptual subtleties and technical difficulties. Recently, in collaboration with Luna, Suzuki, Tomasevic and Way, we have applied novel methods to study the dual dynamical evaporation of a variety of black holes interacting with colder radiation systems. We have also obtained the dual of the collapse of holographic radiation to form a black hole on the brane.
