IAS High Energy Theory Seminar | Adar Sharon, Weizmann Institute of Science | "The Onset of Quantum Chaos in Disordered Systems" | Wolfensohn Hall (behind Bloomberg Hall) & on Zoom

IAS High Energy Theory Seminar | Adar Sharon, Weizmann Institute of Science | "The Onset of Quantum Chaos in Disordered Systems" | Wolfensohn Hall (behind Bloomberg Hall) & on Zoom
Mon, Oct 18, 2021, 2:30 pm

Abstract: We study the Lyapunov exponent in disordered quantum field theories. Generically the Lyapunov exponent can only be computed in isolated CFTs, and little is known about the way in which chaos grows as we deform the theory away from weak coupling.

Fri, Oct 15, 2021, 1:00 pm

Abstract: Neutral atoms trapped in optical tweezer arrays have emerged as a promising platform for quantum simulation and quantum computation. The dynamic reconfigurability of optical tweezer traps enables a high degree of single atom control and the ability to generate large-scale defect-free atom arrays in many geometries.

Mathematical Physics Seminar, Tue, Oct 12, 4:30pm Jadwin A-06, Giorgio Cipolloni, PCTS, "Extension of Wigner's Vision to Quantum Chaos"
Tue, Oct 12, 2021, 4:30 pm

After reviewing recent progress in random Hermitian and non-Hermitian matrix theory, we prove that eigenvectors of Wigner matrices satisfy the Eigenstate Thermalisation Hypothesis (ETH), which is a strong form of Quantum Unique ergodicity (QUE) with optimal speed of convergence.

IAS High Energy Theory Seminar | Holmfridur Hannesdottir, Member, School of Natural Sciences, IAS | "Sequential Discontinuities of Scattering Amplitudes" | Wolfensohn Hall (behind Bloomberg Hall) & on Zoom
Fri, Oct 8, 2021, 1:45 pm

Abstract: In this talk, we explore new techniques to probe the analytic structure of scattering amplitudes in perturbative Quantum Field Theory. The goal of this approach is to leverage symmetries, limits, and analyticity in order to circumvent the explicit evaluation of multi-loop Feynman integrals.

The jet in M87 is likely powered by the supermassive black hole at the center of the galaxy via the Blandford–Znajek (BZ) mechanism, through which energy can be siphoned away from a spinning black hole and converted into a Poynting flux jet.

Abstract: In this talk I will explore the space of solutions to the conformal crossing equations. By recasting the conformal bootstrap as a non-linear optimization problem, we find an efficient way of converging to the solutions of these equations.
