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: 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 […]

Every Tuesday at 2:00 PM in the discussion room on the 5th floor. Join the IFT cosmology/gravity journal club at benty-fields.com to vote for papers and volunteer to present them.
