One of the many remarkable properties of conformal field theory in two dimensions is its connection to algebraic geometry. Since every compact Riemann surface is a projective algebraic curve, many constructions of interest in physics (which a priori...

Phases of quantum many particle systems can have low energy effective field theoretic descriptions in terms of gauge theories in their deconfined phase.
Such emergent gauge theories play a central role in modern theoretical work in condensed matter...

In this talk, I will discuss the Jackiw-Teitelboim model in 2d dilaton gravity in a holographic context. After deriving the boundary time reparametrization equation and the holographic stress tensor, I will demonstrate that these can be obtained...

I will review the efforts made towards approaching string universality in six dimensions and report recent "cartographic" developments on exploring the landscape of six-dimensional string vacua. A working conjecture is that all six-dimensional...

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...

3d {\cal N} = 4 SCFTs have two protected topological sectors, one associated to the Higgs branch and one to the Coulomb branch. I will use supersymmetric localization to derive a Lagrangian description for the 1d sector associated with the Higgs...
