THIS SEMINAR HAS BEEN CANCELLED.

Abstract: I will review the experimental evidence that we have accumulated on physics beyond the Standard Model in the last two decades and draw conclusions on how to move forward. The data point to a scale of new physics far removed from what we...

Abstract: I review some of the many recent advances that have been made in our understanding of perturbative quantum field theory, discuss some of the structural challenges that still exist at loop-level, and outline some of the recent progress...

Abstract: We argue that the large N transseries of a holographic observable above the black hole threshold admits a precision bound, a limit on how precisely the transseries can determine the observable at finite N, set by the data of its D-brane...

Abstract: We discuss new sum rules and inequalities for the cusp anomalous dimensions of conformal line defects, derived from basic principles of quantum field theory. We briefly comment on their applications ranging from gauge theory to...

In this first group meeting of the academic year, we will all introduce ourselves and give a short description of our current research.

The plan for future group meetings is for members, visitors and faculty to give a pedagogical introductory talk on...

Abstract: I will describe a proposal for the CFT dual of the D1-D5-D5' system in the tensionless limit. More specifically, I will consider the case of a single D1-brane, and study the limit in which $g$ $Q_5^\pm \rightarrow 0$, with $g$ the string...

Abstract: The S-matrix bootstrap uses analyticity, unitarity, and crossing symmetry to place nonperturbative bounds on 4-point scattering amplitudes. In my talk, I describe the application of the bootstrap to the scattering of O(4) symmetric scalars...

Abstract: There is a longstanding dream of realizing large-N Yang-Mills theory in D = 3,4 as a theory of confining strings. So far, our knowledge of this putative string is restricted to low energies, where one can use an effective field theory...

Abstract: I will present a class of exactly solvable lattice models of bosonic modes on the square lattice that realize chiral topological phases described by U(1)_{2n}​ Chern-Simons theory. The key ingredient is a factorization of the bosonic...
