Portents of new physics from extreme gravity
William East - Perimeter Institute for Theoretical Physics
Complementing the spectacular breakthroughs in gravitational wave and multi-messenger astronomy, advancements in our theoretical understanding and modelling of the strong gravity are essential to apprehending the nonlinear dynamics of spacetime, and to unlocking the full potential of the… -
Connecting quantum gravity to particle physics and to the dark universe - why and how?
Astrid Eichhorn - Universität Heidelberg
There are fascinating new insights we could achieve if we succeeded in connecting quantum gravity to particle physics in the visible and the dark universe. However, making such a connection is challenging, because the typical scale of quantum gravity is believed to be far from the typical scales in… -
From wave function collapse to non-abelian anyons on a quantum processor
Ruben Verresen - University of Chicago
Schrodinger's thought experiment famously illustrates the dramatic effect of measuring a quantum state. The resulting wave function collapse is often thought to make states more classical and familiar. However, in this colloquium, we explore how measurements can be used as a chisel to efficiently… -
In Search of Lost Spacetime
Chris Smeenk - Western University
The classical spacetime manifold of general relativity disappears in quantum gravity, with different research programs suggesting a variety of alternatives in its place. As an illustration of how philosophers might contribute to an interdisciplinary project in quantum gravity, I will give an… -
Hidden patterns in the standard model of particle physics: the geometry of SO(10) unification
Kirill Krasnov - University of Nottingham
The aim of the presentation is to review the beautiful geometry underlying the standard model of particle physics, as captured by the framework of "SO(10) grand unification." Some new observations related to how the Standard Model (SM) gauge group sits inside SO(10) will also be described. I will… -
Quantum error-correction and quantum gravity
Beni Yoshida - Perimeter Institute for Theoretical Physics
In this colloquium, I will review how the notion of quantum error-correction has transformed our understanding of quantum gravity in the past decade. Zoom link: https://pitp.zoom.us/j/94349082665?pwd=OFdJdkpHU1NEcmlNeW5pWlg4WmNBZz09 -
How to solve quantum many-body problems.
Annabelle Bohrdt - Harvard University
In quantum many-body physics, we aim to understand and predict the exciting phenomena emerging from the interactions of many quantum particles. In this talk I will use the paradigmatic Fermi-Hubbard model, a conceptually simple model of interacting fermionic particles, as an example to highlight… -
Quantum energy teleportation: from theory, to experiments and spacetime engineering
Eduardo Martin-Martinez - University of Waterloo
In 2008 Masahiro Hotta proposed a protocol for transporting energy between two localized observers A and B without any energy propagating from A to B. When this protocol is applied to the vacuum state of a quantum field, the local energy density in the field achieves negative values, violating… -
Language models for many-body physics
Juan Carrasquilla - ETH Zurich
In this talk, I will discuss our work on using models inspired by natural language processing in the realm of many-body physics. Specifically, I will demonstrate their utility in reconstructing quantum states and simulating the real-time dynamics of closed and open quantum systems. Finally, I will… -
The Tenfold Way
John Baez - University of California, Riverside
The importance of the tenfold way in physics was only recognized in this century. Simply put, it implies that there are ten fundamentally different kinds of matter. But it goes back to 1964, when the topologist C. T. C. Wall classified the associative real super division algebras and found ten of… -
An asymptotically safe road to quantum gravity with matter
Marc Schiffer - Radboud Universiteit Nijmegen
I will introduce asymptotically safe quantum gravity, which is based on the quantum realization of scale invariance, as one candidate theory to describe nature at all scales. I will discuss the concept of an asymptotically safe fixed point, and how the realization of scale invariance at high… -
Some recent stuff about the Quantum Approximate Optimization Algorithm
Edward Farhi - Alphabet (United States)
I will introduce the QAOA and discuss some recent developments. These might include the application of the QAOA to the Sherrington-Kirkpatrick model, landscape independence, and the odd behavior when starting in a good place. Zoom link: https://pitp.zoom.us/j/94804346887?pwd…
