TITLES AND ABSTRACTS OF LECTURES AND TALKS
Alexey Isaev (BLTP, JINR, Dubna, Russia)
Title: Dynamical systems – symmetries and exact solutions
Abstract: TBA
Schedule: Thursday, September 8th & September 9th
Daniel Grumiller (TU Wien, Viena, Austria)
Title: Flat space holography
Abstract: While our best realization of the holographic principle is the AdS/CFT correspondence, we would like to understand if holography also works for asymptotically flat spacetimes. These lectures provide an introduction to flat space holography with focus on the Carrollian approach, especially in three bulk dimensions.
Lecture 1: Aspects of AdS/CFT
Lecture 2: Asymptotically flat spacetimes
Lecture 3: Carrollian conformal field theories
Lecture 4: Towards flat space holography
Schedule: Monday, September 7th
Goran Djordjevic (University of Nis, Serbia, Executive Director of SEENET-MTP)
Title: The newest results in Cosmology, Applications of holography. An announcement and introduction to the continuation of the program.
Schedule: Monday, September 7th, 10:15 - 11:00
Kalin Staykov (Sofia University, Bulgaria)
Title: Static and rotating compact stars in general relativity and modified theories of gravity
Abstract: During the lecture we will develop the techniques used to construct static compact objects in general relativity. We will then extend this formalism to scalar–tensor theories of gravity and discuss the construction of numerical solutions in this context. Finally, we will briefly examine differentially rotating neutron stars as realistic merger remnants and the methods used to construct such configurations.
Schedule: Tuesday, September 8th
Marija Tomasevic (CERN, Geneva, Switzerland)
Title: Quantum Aspects of Space and Time
Abstract: Classical general relativity reveals that space and time can behave in striking ways under extreme conditions. Horizons can form, and curvature singularities can arise, yet the latter remain poorly understood. While a complete theory of quantum gravity is still out of reach, we can nevertheless make progress by studying controlled quantum corrections, whether perturbatively in hbar or in other suitable scaling regimes.
In this course, we will explore several settings in which quantum effects substantially modify the classical picture. We will see how inner horizons acquire a universal singular structure, while mild singularities can develop quantum-induced horizons that cloak them. We will also discuss scenarios in which outer horizons can disappear entirely, and how quantum effects can render wormholes traversable. Finally, time permitting, we will examine very cold black holes, where quantum corrections resolve thermodynamic puzzles and sharpen our understanding of black hole microstate counting.
