All physical phenomena in areas such as physics, engineering, finance, and biology are inherently nonlinear and therefore described via models of nonlinear partial differential equations (PDEs). The Navier-Stokes and the Euler equations are thought to be the fundamental set of equations governing the motion of fluid flow. Recently, the research area related to fluid flow equations  has witnessed multiple seminal new results and groundbreaking techniques. The main aim of the program is to bring in leading researchers from the field of fluid mechanics for an active discussion on these new techniques and exchange of ideas. In his celebrated 1949 paper on statistical hydrodynamics Lars Onsager conjectured that the threshold regularity for the validity of energy conservation of weak solutions to Euler equations is the exponent 1/3. In particular he announced that for larger Hölder exponents any weak solution would conserve the energy, whereas for any smaller exponent there are solutions whi...

Understanding causality is fundamental to science and inspires wide-ranging applications, yet there are several distinct notions of causation. Recently, there have been important developments on the role of causality in quantum physics, relativistic physics and their interplay. These have unearthed a plethora of fascinating open questions regarding the nature of causation, emergence of space-time structure and the limits of quantum information processing. At the same time, causal reasoning has become an important tool in machine learning and statistics, with applications ranging from big data to healthcare. This conference brings together experts from different areas of physics working on questions related to causality, as well as selected researchers who bridge the gap between fundamental research and current industrial applications. The aim of the conference is to provide a venue for cross-pollination of these ideas through scientific exchange between these communities. The conference will focus on the following facets of causality:

 

• Quantum and classical causal inference

• Indefinite causal order and quantum reference frames

• Causality in quantum field theory and quantum gravity

• Experiments and applications of causality

The annual Graduate Students’ Conference showcases the diverse research directions at Perimeter Institute, both organized and presented by the students. Our graduate students are invited to share their best work with their fellow PhD students, PSI students and other PI residents interested in hearing about physics research and discussing it in a lively atmosphere full of questions.

PSI students are welcome to join as audience members on Friday, Sept 13 and to present a Lightning Talk if they wish to do so.

Chromatin is a long polymer in which the genetic code is intricately arranged in 4D (space and time). Beyond the DNA sequence, the epigenetic state and 3D organization of chromatin dictate the gene regulation in a spatio-temporal manner.The study of chromatin is at a juncture where recent advances in genomics, high-resolution microscopy, and single-cell level measurements have made it possible to understand the underlying principles behind this complex organization and gene regulation.Integrating this diverse information into a coherent understanding requires multi-disciplinary expertise, and this meeting aims to facilitate such cross-talks between specialists from different fields. Discussions during the meeting on novel experimental observations and phenomenology, along with physical principles and data-driven methods, are expected to benefit the diverse community interested in chromatin.The first week will be a pedagogical workshop that will cover diverse experimental and theoretica...

This advanced level school is the fifteenth in the series and will be organized jointly by the International Centre for Theoretical Sciences (ICTS) and the Raman Research Institute (RRI).This is a pedagogical school, aimed at bridging the gap between masters-level courses and topics in statistical physics at the frontline of current research. It is intended for Ph.D. students, post-doctoral fellows and interested faculty members at the college and university level. The following courses will be offered.1) Bruno Loureiro - Statistical Physics of Machine Learning (Online)2) Deepak Dhar - Introduction to Percolation Theory3) Massimiliano Esposito - Macroscopic Stochastic Thermodynamics4) Gregory Falkovich - Information Theory5) Prabha Mandayam - Bell's Inequalities and Quantum Entanglement6) P.

The aim of the first part is to present a brief overview of selected topics in quantum theory. Schrodinger, Heisenberg and Interaction picture is discussed and applied to study time evolution. Density matrix and Feynman path integral are introduced. The second part of the course derives the Feynman rules for scalar quantum field theory and introduces renormalization. Instructor: Bindiya Arora / Dan Wohns Students who are not part of the PSI MSc program should review enrollment and course format information here: https://perimeterinstitute.ca/graduate-courses

This is a theoretical physics course that aims to review the basics of theoretical mechanics, special relativity, and classical field theory, with the emphasis on geometrical notions and relativistic formalism, thus setting the stage for the forthcoming courses in Quantum Mechanics, and Quantum Field Theory in particular, as well as in General Relativity and Quantum Gravity.

The study of zero mean curvature surfaces in $\mathbb{R}^3$ (minimal surfaces) has witnessed significant progress since its initiation over 200 years ago. However, the topics of maximal surfaces (ZMC surfaces) in the Lorentz-Minkowski space and ZMC surfaces in hyperbolic spaces,  are relatively recent. The proposed meeting on Zero Mean Curvature surfaces aims to bring together leading experts in the areas  to discuss a wide range of topics- new challenges, problem-solving methodologies. Early-career researchers will have the opportunity to engage with the most significant and promising problems within these domains. This discussion meeting is intended to inspire faculty, students, and postdocs to delve into this vibrant and evolving field of research.During the five-day discussion meeting, the final day will be reserved for open discussions to encourage potential collaborations. There will be mini-courses by subject experts of introductory nature for younger researchers, who are  not e...
