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

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.

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.

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

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.

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.

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.
