Speaker: Eduardo García-Valdecasas (SISSA, Trieste) Venue&Time: Red Room / 15:00 Abstract: Entanglement asymmetry is a relative entropy that faithfully measures the breaking of a symmetry in a subregion. We explore some applications in theories with spontaneously broken higher form symmetries. We will start with discrete abelian symmetries and then discuss continuous symmetries. We will be […]
Every Tuesday at 15:00 in Grey Room 3.
Speaker: Aram Harrow (MIT) Venue&Time: Grey Room 3 / 11:30 Abstract: Given a vector v, what is the closest k-sparse vector? The answer to this question is usually that we should take the largest k entries of v. It turns out that we can do better with randomized approximations. When approximating pure bipartite entangled states […]
Speaker: Matteo Lotito (IFT) Venue&Time: Red Room / 12:00 Abstract: I present a brief summary of the derivation of the Weak Gravity Conjecture within perturbative string theory, following , and highlight possible gaps that may hinder a fully consistent proof. I then analyze the existence and properties of the black hole solutions whose extremality bounds […]
Pablo Blanco (IFT) will present Neutrino Masses and Mixings in Gauge Models with Spontaneous Parity Violation de Rabindra N. Mohapatra, Goran Senjanovic, Jul, 1980 Phys.Rev.D 23 (1981) 165. Abstract: Unified electroweak gauge theories based on the gauge group SU(2)L×SU(2)R×U(1)B−L, in which the breakdown of parity invariance is spontaneous, lead most naturally to a massive neutrino. […]
Speaker: Anthony Zee from Kavli Institute for Theoretical Physics and the Departmentof Physics, University of California, Santa Barbara, CA, USA Venue&Time: Red Room / 3:00 PM Abstract: I will list and discuss the ten foundational ideas of theoretical physics. The lecture is based on a popular book with the same title published by Princeton University […]
The IBS-IFT Workshop is a regular event organized jointly by IFT and IBS-CTPU, this year reaching its tenth anniversary. The aim of the workshop is share ideas, foster collaborations, and to discuss recent developments in theoretical physics. The event is organized over two weeks. The first week, November 4-7, will focus on String Phenomenology The Center […]
Speaker: Sounak Pal (Indian Institute of Technology) Venue&Time: Grey Room 3 / 11:30 Abstract: I will discuss some aspects of 2D and 3D quantum gravity in the language of Topological quantum field theory (TQFT). Recent developments include calculating various gravity partition functions in AdS3 using descriptions of Liouville conformal field theory (CFT). We extend this […]
