Strategies for solving the Fermi-Hubbard model on near-term quantum computers
The Fermi-Hubbard model is of fundamental importance in condensed-matter physics, yet is extremely challenging to solve numerically. Finding the ground state of the Hubbard model using variational methods has been...

Homological mirror symmetry for the universal centralizers
I will present recent work (to appear soon) on the homological mirror symmetry about the universal centralizers $J_G$, for any complex semisimple Lie group $G$. The A-side is a partially...

Symmetries at Null Boundaries
I will present and motivate a program establishing, in full generality, the symmetries and charge analysis for gravitational theories near a generic null hypersurface without specifying any boundary condition. I...

Mixed-state entanglement as a diagnostic for quasiparticles and finite-T topological order
Quantum entanglement of pure states has led to new insights into a wide variety of topics. Entanglement of mixed states is however less well understood. In this talk I will...

Analytic calculation of the power spectrum covariance: speedup by four orders of magnitude
In order to infer cosmological parameters from galaxy survey data, we typically use summary statistics such as the power spectrum and we need an accurate estimate of their covariance matrix...

Is SMEFT Enough?
The four scalar degrees of freedom of the Standard Model, the Higgs and the longitudinal components of the Ws and Z, are amenable to different EFT descriptions. "SMEFT" wraps them...

Inside the Hologram: The bulk observer's experience
I will present a holographic framework for reconstructing the experience of bulk observers in AdS/CFT. In particular, I will show how to recover the proper time and energy distribution measured...
