The Universe from a single Particle - Michael Freedman - Microsoft Q

Mon, Nov 1, 2021, 4:30 pm

I will explore a toy model for our universe in which spontaneous symmetry breaking – acting on the level of operators (not states) - can produce the interacting physics we see about us from the simpler, single particle, quantum mechanics we study as undergraduates.

HET Seminar | | Henriette Elvang, University of Michigan | "Bootstrap of the KLT Double-Copy" | via Zoom

Mon, Nov 1, 2021, 2:30 pm

In field theory, the "double copy" can be thought of as a multiplicative map between tree amplitudes of two field theories into tree amplitudes of another theory. This map has an identity element that is closely linked to the multiplication kernel that defines the KLT formulation of the double-copy.


PGI Fall Seminar Series| Keefe Mitman|Caltech| "Gravitational Waves in Numerical Relativity and the Importance of BMS Frames"

Biophysics Seminar: Alison Sweeney, Yale University| The Physical Design of Optimum Solar Resource Utilization in Giant Clams

Mon, Nov 1, 2021, 12:30 pm

Photosynthesis presents a paradox of solar energy: the maximum quantum efficiency of photosystem II likely surpasses that of any engineered system, but in environments with high solar flux, photosynthetic organisms are famously wasteful and resource inefficient.

Audience: A free lecture open to the public.

Princeton Quantum Colloquium: "Benchmarking Analog Quantum Simulators based on Emergent Randomness," Soonwon Choi (MIT)

Mon, Nov 1, 2021, 12:30 pm

Abstract: Recent advances in experiments allowed us to simulate a variety of interesting quantum many-body phenomena from thermalization and localization to universal scaling across phase transitions.


FPO- Brian Trundy, "“Real and p-adic Physics”

Fri, Oct 29, 2021, 3:00 pm

Abstract: This thesis examines the consequences of non-Archimedean geometry in holography and many-body physics. In this framework real space is replaced by a non-Archimedean field which is almost always a padic field or an algebraic extension of a p-adic field. The corresponding bulk geometry is replaced by a discrete tree.


IAS HET Seminar | Venkatesa Chandrasekaran, Member, School of Natural Sciences, IAS | "The Area Operator in Gravity and Holography" | Wolfensohn Hall (behind Bloomberg Hall) & on Zoom

Fri, Oct 29, 2021, 1:45 pm

Abstract:  The area operator plays a central role in our understanding of holography and black hole thermodynamics. In this talk I will discuss a formulation of the area operator at the level of classical gravity, the “kink transform”, which defines a notion of a half-sided boost of gravitational initial data.


PRISM/PCCM SEMINAR: Elastohydrodynamic Friction: From Colloidal Networks to Haptic Materials

Wed, Oct 27, 2021, 12:00 pm

Abstract: The need to understand friction fundamentally at the microscale is increasingly important in technologies as diverse as soft robotics and consumer products. The first part of the talk focuses on the role of particle roughness in the rheology, structure, and dynamics of dense colloidal suspensions.


Mathematical Physics Seminar, Tues, Oct 26, 4:30pm, Jadwin A06, Terry Loring, University of New Mexico, “EMERGENT TOPOLOGY FROM FINITE VOLUME TOPOLOGICAL INSULATORS”

Tue, Oct 26, 2021, 4:30 pm

Finite volume (or area) models for topological insulators are closer to experiment than in_nite volume models. However, they are only indirectly connected to Brillouin zone and so we need to look elsewhere for a topological space.


Special IAS HET Seminar | Nima Arkani-Hamed, Professor, School of Natural Sciences, IAS | "Spacetime and Quantum Mechanics; Particles and "Strings"; Polytopes, Binary Geometries and Quiver Categories" | Wolfensohn Hall (behind Bloomberg Hall) & on Zoom

Tue, Oct 26, 2021, 1:30 pm

Abstract: The past decade has seen the emergence of surprising new connections between the real-world physics of elementary particle scattering processes, and simple new mathematical structures in combinatorics, algebra and geometry.


CM/AMO Seminar/Spin dynamics of ultracold atoms in optical lattices/Wolfgang Ketterle, MIT

Tue, Oct 26, 2021, 12:30 pm

Ultracold atoms offer a unique platform to perform quantum simulations of quantum materials and many-body systems.  When atoms with spin are arranged in an optical lattice in form of a Mott insulator, they realize paradigmatic Heisenberg spin models, where only neighboring spins interact.  Until very recently, all experimental studies with cold...

IAS HET Seminar | Michael Levin, University of Chicago | "Lattice Edge Theories for Topological Phases of Matter" | Wolfensohn Hall (behind Bloomberg Hall) & on Zoom

Mon, Oct 25, 2021, 2:30 pm

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.

Biophysics Seminar: Jeanne Stachowiak|The University of Texas at Austin|Disordered protein networks as synergistic drivers of membrane traffic

Mon, Oct 25, 2021, 12:30 pm

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

Audience: A free lecture open to the public.

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

Mon, Oct 25, 2021, 12:30 pm

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"

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.


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

Fri, Oct 15, 2021, 1:45 pm



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

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.
