Generalized Siegel-Weil formula, Chern-Simons invariants and 3d gravity

Speaker:	Abhiram Kidambi (Kavli IPMU, University of Tokyo)
Abstract:	A recent discovery in holography is the idea of a dual not of a particular CFT but rather of an ensemble of CFT's and its gravitational interpretation. In this talk, I will explain the case of the generalization of the recent work of Maloney-Witten and Afkhami-Jeddi et.al. Following a pedagogical introduction to the number theory requirements, I will talk about the holographic duality that follows from considering the average over toroidal CFTs with unequal left and right moving central charges.

A novel laser spectroscopy technique to explore the most exotic nuclides

Speaker:	Dr. Simon Lechner (CERN)
Abstract:	More than 70 years after the establishment of the nuclear shell model, understanding the rich physics phenomena encountered in atomic nuclei across the nuclear chart remains an intriguing endeavor of research. Radioactive ion beam (RIB) facilities such as ISOLDE at CERN enable studies of short-lived radioactive isotopes in order to improve and benchmark modern nuclear theory. A powerful tool to access nuclear ground state properties of radionuclides, such as the nuclear spin, electromagnetic moments and charge radii, is collinear laser spectroscopy (CLS). However, in order to explore the most exotic nuclides far away from stability, more sensitive methods are needed. For this reason, the novel MIRACLS project at ISOLDE/CERN, aims to...
