Entanglement entropy of highly excited eigenstates of many-body lattice Hamiltonians
The average entanglement entropy of subsystems of random pure states is (nearly) maximal. In this talk, we discuss the average entanglement entropy of subsystems of highly excited eigenstates of integrable...

Explicit quantum weak coin flipping protocols with arbitrarily small bias
We investigate weak coin flipping, a fundamental cryptographic primitive where two distrustful parties need to remotely establish a shared random bit. A cheating player can try to bias the output...

Affine Beilinson-Bernstein at the critical level for GL_2
There has long been interest in Beilinson-Bernstein localization for the affine Grassmannian (or affine flag variety). First, Kashiwara-Tanisaki treated the so-called negative level case in the 90's. Some ten years...

Homology of the affine Grassmannian and quantum cohomologies
Let G be a complex reductive group, and X be any smooth projective G-variety. In this talk, we will construct an algebra homomorphism from the G-equivariant homology of the affine...

Rebooting Canonical Quantum gravity
In this talk, we present a new outlook on canonical quantum gravity and its coupling to matter. We will show how this fresh perspective combines the critical elements of holography...

Magic-angle twisted bilayer graphene at charge neutrality: interactions and disorder
Stacking two graphene layers twisted by the ‘magic angle’ 1.1º generates flat energy bands, which in turn catalyzes various strongly correlated phenomena depending on filling and sample details. While this...

Searching for New Physics Across the Spectra
Theories beyond the Standard Model of particle physics often predict new, light, feebly interacting particles whose discovery requires novel search strategies. A light particle, the QCD axion, elegantly solves the...

The Second Mission of Supersymmetry: Miracles in Uncharted Waters
In our four-dimensional world supersymmetry is the only extension of the classical Poincaré invariance which laid the foundation of modern physics in the beginning of the 20th century. Supersymmetry, a...

Geometry and 5d N=1 QFTs
I will explain that a geometric theory built upon the theory of complex surfaces can be used to understand wide variety of phenomena in five-dimensional supersymmetric theories, which includes the...
