During the semester we have a high energy seminar and a lunch seminar. In addition to these two seminars we participate in a joint theoretical high energy theory seminar in Newe Shalom. The joint seminar takes place on Tuesdays from 10:30 until 13:30 and includes two talks and lunch. This seminar is attended by the high energy groups of all the Israeli institutions and usually attracts a crowd of roughly twenty participants.

Title: Complexity for CFTs in General Dimensions
Abstract: In this talk, I will discuss circuit complexity for conformal field theory states in arbitrary dimensions. The circuits start from a primary state and move along a unitary representation of the Lorentzian conformal group. I will consider different choices of distance functions and explain how they can be understood in terms of the geometry of coadjoint orbits of the conformal group. This analysis will highlight a connection between the coadjoint orbits of the conformal group and timelike geodesics in anti-de Sitter spacetimes, with interesting implications regarding the holographic complexity proposals. This is based on a work with Nicolas Chagnet, Jan de Boer and Claire Zukowski.

Title: Emergent symmetries in 3d and compactification from 5d
Abstract: We study the phenomenon of symmetry enhancement in quantum field theories in three dimensions, where the global symmetry of a model is larger in the IR than in the UV. We focus on supersymmetric theories where the situation is more tractable,and find an organizing principle for such enhancements in the form of compactifications of 5d theories on Riemann surfaces with flux in their global symmetries. We illustrate this by considering the compactification of the so-called 5d Seiberg SCFTs on tori,and obtain 3d theories with enhanced IR symmetries given by the 5d symmetry preserved by the chosen flux.
