The Emperor's New Crown: What Covid-19 Reveals
As of late March 2020, Covid-19 has already secured its status among the most expansive pandemics of the last century. Covid-19 is caused by a coronavirus--SARS-CoV-2--that causes a severe respiratory...

Gravitational edge modes: From Kac-Moody charges to Poincaré networks
In this talk I revisit the canonical framework for general relativity in its connection-frame field formulation, exploiting its local holographic nature. I will show how we can understand the Gauss...

ISCOs in AdS/CFT
I describe a novel way to produce states associated to geodesic motion for classical particles in the bulk of AdS that arise from particular operator insertions at the boundary at...

Toward a Quantum-Safe Future
There has been tremendous progress in the many layers needed to realize large-scale quantum computing, from the hardware layers to the high level software. There has also been vastly increased...

Baby Universes and Black Hole Information
In the 1980’s, work by Coleman and by Giddings and Strominger linked the physics of spacetime wormholes to ‘baby universes’ and an ensemble of theories. We revisit such ideas, using...

Exploring the nonlinear dynamics of Einstein dilaton Gauss-Bonnet gravity
We discuss several numerical and analytical studies of the modified gravity theory Einstein dilaton Gauss-Bonnet (EdGB) gravity. This class of modified gravity theories admit scalarized black hole solutions. The theory...

Coulomb branches for quaternionic representations
I will review the construction of Coulomb branches in 3D gauge theory for a compact Lie group G and a quaternionic representation E. In the case when E is polarized...

Quantum group in 3d quantum gravity
It is well-known that quantum groups are relevant to describe the quantum regime of 3d gravity. They encode a deformation of the gauge symmetries (Lorentz symmetries) parametrized by the value...
