Abstract: Understanding holography as a quantum error-correcting code obeying the JLMS relation has been central to entanglement wedge reconstruction. Previous analyses have focused on a small code subspace of perturbative bulk states around a fixed...

Abstract: For a quantum field of arbitrary mass and spin in the static patch of de Sitter spacetime, the Euclidean partition function receives contributions from edge modes localized on the horizon, expressible in terms of the Harish-Chandra...

Abstract: Gently stir a fluid in a large box sitting still. This talk is about the behavior of turbulence that is generated. We report results of large numerical simulations of the Navier-Stokes equations in a triply periodic box---and compare the...

Abstract: I will discuss the quantum resource known as magic and its analysis in many-fermion systems such as the Sachdev-Ye-Kitaev model. I will show that the SYK calculation of magic can be quantitatively modeled with a gravity calculation...

Abstract: We propose a Hamiltonian framework for constructing chiral gauge theories on the lattice based on symmetry disentanglers: constant-depth circuits of local unitaries that transform not-on-site symmetries into on-site ones. When chiral...

Abstract: I will employ twistor string theory to construct a bulk dual of N = 4 super Yang-Mills in the regime of weak 't Hooft coupling. I will also discuss applications of this duality to the study of scattering amplitudes, giant graviton...

Abstract: It is believed that topologically ordered gapped local Hamiltonians in 2+1d consisting of commuting terms may not realize a chiral anyon theory. There is even a formula that expresses the chiral central charge of the edge theory as an...

Abstract: Conformal field theories in 3D are central to condensed-matter and high-energy physics. Among them, critical gauge theories, especially Chern-Simons-matter theories, stand out: They describe transitions where one or both phases are...

Abstract: Entanglement Bootstrap is a research program to understand and extract the universal data of quantum many body states from local entanglement information.  Since this universal data is usually encoded in a quantum field theory, the program...

Abstract: In a spacetime with asymptotically anti-de-Sitter boundaries, localized bulk events produce characteristic signals at boundary locations that are lightlike from the event. I will describe (thought) experiments that use boundary wavepackets...
