**Abstract:** Edge excitations of (2+1)D topological phases are usually described using continuum field theories. But the boundaries of some (2+1)D topological phases can also be described using lattice-like edge theories that have a finite dimensional Hilbert space for a finite size boundary.

Membrane curvature is required for many cellular processes, from assembly of highly curved trafficking vesicles to extension of needle-like filopodia.

### PGI Fall Seminar Series|Alejandro Cárdenas-Avendaño|Princeton University|"Quantifying the Unknown Using Electromagnetic and Gravitational Observations of Compact Objects"

Abstract: Over the past years, electromagnetic and gravitational observations have been used to understand the nature of compact objects and the matter around them.

### High Energy Experimental Physics Seminar- Dan Zhang UMD- "Dark Matter Search in PandaX-4T Commissioning Run"

Abstract:

### 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

**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.

### HET Seminar | Clifford Johnson |, USC/Princeton | "The Microstate Physics of JT gravity" | PCTS & Zoom

Abstract:

### FPO- Samuel Saskin, "Building Quantum Systems with Ytterbium Rydberg Arrays"

**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.

### PRISM/PCCM Webinar: Bespoke Biomaterials: Towards Personalized Tissue Mimics

Registration is required. You can register for this webinar using this form here.

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

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.

### HET Seminar | Patrick Jefferson, MIT | "New perspectives on 4D N=1 F-theory flux vacua with chiral matter" | PCTS 407 & via Zoom

Abstract:

### PGI Fall Seminar Series|Zimo Sun|Princeton University| "Harish-Chandra characters, de Sitter Quasinormal Modes and Sphere Partition Functions"

Abstract: Harish-Chandra characters generalize the ordinary group characters to infinite dimensional representations of noncompact Lie groups.

### 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

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.

### Hamilton Colloquium Series, Howard Stone, Princeton University, "Classical fluid mechanics confronts modern research questions: Virus transport, a novel similarity solution, and an N-body problem"

I will provide a brief overview of recent projects in my group where we identify new analytical and physical features of flows common to modern research questions.

### Mathematical Physics Seminar, Jeffrey Schenker, Michigan State University, "Theory of Ergodic Quantum Processes"

Any discrete quantum process is represented by a sequence of quantum channels.

### PGI Fall Seminar Series|George Wong|Princeton University| "Probing Black Hole Spin and the Black Hole–Jet Connection"

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.
