Swamplandish Predictions for our Universe
Cumrun Vafa - Harvard University
In this talk I show how simple ideas motivated from the Swampland program, lead to concrete predictions for our universe. These include predictions for particle physics and cosmology. I also discuss some experimental predictions for these ideas. --- Zoom link -
Realization and Characterization of Topological States on Quantum Processors
Frank Pollmann - Technical University of Munich (TUM)
The interplay of quantum fluctuations and interactions can yield novel quantum phases of matter with fascinating properties. Understanding the physics of such systems is a very challenging problem as it requires to solve quantum many body problems—which are generically exponentially hard to solve on… -
Anomalously fun: aspects of many-body quantum kinematics
Chong Wang - Perimeter Institute for Theoretical Physics
A fundamental result in solid-state physics asserts that a crystalline material cannot be insulating unless the number of electrons per unit cell is an integer. Statements of this nature are immensely powerful because they are sensitive only to the general structure of the system and not to the… -
Dual Theory of Decaying Turbulence
Alexander Migdal - New York University Abu Dhabi
We investigate the recently found \cite{migdal2023exact} reduction of decaying turbulence in the Navier-Stokes equation in $3 + 1$ dimensions to a Number Theory problem of finding the statistical limit of the Euler ensemble. We reformulate the Euler ensemble as a Markov chain and show the… -
Stars under Einstein’s microscope: strong gravitational lensing near caustics
Liang Dai - University of California, Berkeley
Rich clusters of galaxies are the largest gravitational magnifiers in the Universe. One of the most interesting gravitational lensing phenomena arises when background galaxies overlap with the lensing caustics cast by the cluster lens, such that a portion of it is tremendously magnified by hundreds… -
Tiny universes from ensembles of open quantum systems
Sarah Shandera - Pennsylvania State University
Gravity creates space-time boundaries that limit observables without limiting the flow of energy and information. This means that quantum systems in cosmology are often open systems: to describe them we must include the effects of interaction with an unobservable environment. In many cosmological… -
Clocks and precision measurements with ultracold molecules
Significant advancements in our understanding of the physical world have been driven by increasingly precise atomic spectroscopy. The level of accessible precision entered a new realm with the advent of laser cooling and trapping. Now we can extend the ultrahigh spectroscopic precision, or atomic… -
Homotopy theory and quantum field theories
Mayuko Yamashita - Perimeter Institute for Theoretical Physics
Recently, there has been a growing interest in the relations between homotopy theory in mathematics and theoretical physics. Homotopy theory is used to classify and study physical systems. Also, physically motivated conjectures have led to many interesting developments in homotopy theory. I have… -
Physics Meets Geometry: a fuzzy sphere Odyssey in critical phenomena
Yin-Chen He - Stony Brook University
Historically, the synergy between physics and geometry, from the times of Archimedes and Newton to the era of Einstein, has repeatedly been the catalyst for pivotal breakthroughs in physics and mathematics. In this talk, I will introduce a new narrative demonstrating how physics and geometry… -
Deep Probabilistic Models for Cosmological Analysis and Beyond
Biwei Dai - University of California, Berkeley
Current and future weak lensing surveys contain significant information about our universe. However, their optimal cosmological analysis is challenging, with traditional analyses often resulting in information loss due to reliance on summary statistics like two-point correlation functions. While… -
Cosmological dynamics of light dark bosons
Junwu Huang - Perimeter Institute for Theoretical Physics
Light bosons, including light axions, dark photons, and dilaton/moduli, are well motivated extensions to the Standard Model of particle physics and intriguing dark matter candidates. Much progress has been made in recent years in both astrophysical and lab searches for these light bosons with the… -
Algebraic geometry at the limits of perturbative QFT and dark matter in moduli spaces
Michael Borinsky - Perimeter Institute for Theoretical Physics
Feynman diagrams and the associated integrals are crucial in perturbative quantum field theory for translating theory input into concrete, observable quantities. I will talk about the fascinating interplay of physics and mathematics that emerges from the ensemble of these diagrams. From linear…
