At the end of this lecture we give feedback about those presentations. What is X and what is Y depends on how many students volunteer to present. Of course, people who just want to attend without presenting are also most welcome! Location: Alice Room, 3rd Floor, Perimeter Institute, 31 Caroline St N, Waterloo Recording/Zoom Details: Lectures will be recorded for PIRSA; Zoom link will be provided to registered participants. Building Access: Participants who do not have an access card for Perimeter Institute must sign in at the security desk before each session. When attending the lectures you can use the free self-serve coffee/water station on the ground floor. Meals and snacks at the on-site Black Hole Bistro are available at the full menu cost.

The aim of this course is to explore the main ideas of the statistical physics approach to critical phenomena. We will discuss phase transitions, using the ferromagnetic phase transition and the Ising model as our primary example, with particular emphasis on the renormalisation group approach. Instructor: Emilie Huffman / Maite Dupuis Students who are not part of the PSI MSc program should review enrollment and course format information here: https://perimeterinstitute.ca/graduate-courses

The first half of the course explains why fields are desirable when quantum mechanics meets special relativity. The second half introduces different kinds of spinor fields and their interactions. Instructor: Gang Xu 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. Instructor: Aldo Riello Students who are not part of the PSI MSc program should review enrollment and course format information here: https://perimeterinstitute.ca/graduate-courses

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.

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

Important dates
Paper submission deadline: 24 May 2024 // 31 May 2024
Paper notification: 3 July 2024 Registration deadline (with application for financial assistance): 18 July 2024
Registration deadline: 28 August 2024
Conference: 16-20 September 2024   Update: The submission deadline has been extended to 31st May 2024 for
papers which clearly justify their relevance for the following three
topics:  1) classical causal inference,  2) causality in relativistic physics (including quantum field theory and quantum gravity) and  3) experiments in causality.    As we have received a sufficiently high number of submissions on the remaining topics (particularly indefinite causality and quantum causal models), the original deadline of 24th May still holds for submissions in this category.   ::  ::  ::
  Call for Abstracts

Prospective speakers can submit a paper for a contributed talk (in person or online) and/or a poster (in person only) via the Call for Abstracts. The Call for Abstracts is now open! Submissions for a talk will automatically be considered for a poster if not accepted for a talk.

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.

Perimeter Institute is happy to host the inaugural summer school for the Simons Collaboration on Celestial Holography July 22-26 in Waterloo, ON. The program will feature lectures on background material relevant for graduate students and postdocs interested in this emerging subfield, paired with vision talks on exciting future research directions.

Recent years have seen a flood of new data, from gravitational wave observations of merging black holes and neutron stars to precision probes of cosmology, which allow for unprecedented tests of our understanding of gravity. Going hand-in-hand with this, there has been significant recent progress on the theoretical side in terms of formulating modified theories of gravity, and using them to make detailed predictions, including in the nonlinear and dynamical regime, which can be confronted with the observations. 

We are excited to announce a landmark conference that plans to delve into the forefront of research on modified theories of gravity and brings together leading experts from different disciplines including observational astrophysicists, numerical relativists, cosmologists and mathematical physicists to explore the present status of modified theories of gravity and envision their future theoretical development and implications for observations.

This conference is also timed to coincide with the 50th anniversary of pioneering work in this area carried out by Gregory Horndeski in the Waterloo Mathematical Physics Community. Hosted jointly by Perimeter Institute and the University of Waterloo, this conference will serve as a forum for researchers from different disciplines to exchange ideas at the cutting
edge of gravitational physics.

The dialogue between quantum information and quantum matter has fostered notable progress in both fields. Quantum information science has revolutionized our understanding of the structure of quantum many-body systems and novel forms of out-of-equilibrium quantum dynamics. The advances of quantum matter have provided novel paradigms and platforms for quantum information processing.
This conference aims to bring together leading experts at the intersections of quantum information and quantum matter. Key topics include: (i) quantum error correction, (ii) quantum dynamics, and (iii) quantum simulation.
