The traversable wormhole protocol of Gao, Jafferis and Wall gives us a glimpse behind the horizon of certain black holes. I will describe this effect and discuss some limited applications to the black hole information problem. Based on a recent...

We present recent developments in F-theory compactifications and focus on advances in constructions of globally consistent F-theory compactifications with Abelian and discrete gauge symmetries, emphasizing technical advances and insights into higher...

I formulate the conformal crossing equation in a way that manifests the conformal representation theory. In this form the crossing equation can be generalized to any group. Using SU(2) as a toy model I compute solutions to the crossing equation in...

I will present the concept of a “BPS graph” (a special kind of spectral network) and illustrate its usefulness in the study of theories of class S. BPS graphs encode BPS quivers, even for higher rank and in the presence of non-full punctures, and...

I'll describe the cluster partition function (CPF), a computational tool that uses elements from cluster algebra and representation theory to describe the partition function of Chern-Simons theory with gauge group SL(N,C), on knot complements. I'll...

The last years have seen remarkable progress in understanding the scattering amplitudes of massless particles in arbitrary dimension. They exhibit structures and a simplicity completely obscured by the Feynman diagram approach, and can be shown to...

I will briefly review our current experimental knowledge of dark matter and then discuss recent developments in model building. In particular I will show that dark matter can be a thermal relic exponentially lighter than the weak scale without being...

The Ryu-Takayanagi formula and its quantum-corrected version are useful in understanding many aspects of quantum gravity such as subregion duality, emergence of the radial direction, and the generalized second law. In this talk, I will first...
