The course begins by discussing several topics in equilibrium statistical physics including phase transitions and the renormalization group. The second part of the course covers non-equilibrium statistical physics including kinetics of aggregation, spin dynamics, population dynamics, and complex networks.

The goal of this conference is for quantum matter researchers at Perimeter, University of British Columbia, and University of Toronto to share their recent work with each other, to facilitate discussion and collaboration.

Perimeter Institute is located on the Haldimand Tract. After the American Revolution, the tract was granted by the British to the Six Nations of the Grand River and the Mississaugas of the Credit First Nation as compensation for their role in the war and for the loss of their traditional lands in upstate New York. Of the 950,000 acres granted to the Haudenosaunee, less than 5 percent remains Six Nations land. Only 6,100 acres remain Mississaugas of the Credit land.

This course uses quantum electrodynamics (QED) as a vehicle for covering several more advanced topics within quantum field theory, and so is aimed at graduate students that already have had an introductory course on quantum field theory. Among the topics hoped to be covered are: gauge invariance for massless spin-1 particles from special relativity and quantum mechanics; Ward identities; photon scattering and loops; UV and IR divergences and why they are handled differently; effective theories and the renormalization group; anomalies.

Join us on Monday October 24 to welcome our new cohort of postdocs at Perimeter Institute at the Postdoc Welcome 2022! Each new postdoc will be given 5 minutes to introduce themselves to the PI Community.  The time will be used to tell us a little bit about themselves and to showcase their current research.  These presentations are very casual and should not be misconstrued as formal talks. Some discussion will follow the presentations, whereby current PI Residents may have the opportunity to ask questions.

Conference Schedule:

9:30AM - 11AM - short talks session 1 in Sky room.
11:00AM -11:30AM - coffee break in 1st floor Bistro
11:30AM - 1:00PM - short talks session 2 in Sky room.
1:00PM - 2:00PM - group lunch in the Bistro in 2nd floor Bistro (new postdocs, postdoc reps)
2:00PM - 5:30PM - off-site activity (new postdocs, existing postdocs)

Join us for a day that celebrates the advance of human knowledge!  Come and hear from scientific luminaries responsible for defining the modern landscape of physics and working to transform it in the future.  Presentations by Nobel and Breakthrough Prize winners will describe some of the most exciting topics in science today, followed by talks by Perimeter researchers on how these are being pursued now, and culminating with animated panel conversations on how breakthrough science was, is and will be done.

This is an introductory course on general relativity (GR). We shall cover the basics of differential geometry and its applications to Einstein’s theory of gravity. The plan is to discuss black holes, gravitational waves, and observational evidence for GR, as well as to cover some of the more advanced topics.

The course starts by looking for a quantum theory that is compatible with special relativity, without assuming fields are fundamental. Nevertheless fields turn out to be a very good, maybe inevitable mathematical tool for formulating and studying such a relativistic quantum theory. The second part of the course introduces the Dirac theory and canonically quantizes it. It also quantizes the Maxwell field theory. The Feynman diagram technique for perturbation theory is developed and applied to the scattering of relativistic fermions and photons. Renormalization of quantum electrodynamics is done to one-loop order.

Prerequisite: PSI Quantum Theory course or equivalently Graduate level Quantum Mechanics and QFT of scalar theory

There has been recent activity in looking for new conserved charges and symmetries in gravity, most notably at infinity but also for finite regions. An important question is whether some of these charges and symmetries have physical implications. These charges are evaluated on codimension-2 surfaces  called corners, which constitute the main focus of this conference. The goal is to bring together leading experts and promote discussions and exchanges among different approaches to (quantum) gravity.

This School aims at bringing together graduate students and junior postdocs, both theorists and experimentalists, who are interested in proposing and realizing new table-top experiments to test fundamental physics. The goal is to allow them to interact and learn from each other, forming a community.

The School will consist of some theoretical lectures for experimentalists, and experimental lectures for theorists. The scope is to offer basic and relevant notions of each field to physicists with a different background, in order to fill some of the gaps of the respective academic curricula.

The theoretical lectures will cover a review of the Standard Model with emphasis on precision tests, such as the search of new long-range forces and of electrical dipole moments. Another main topic will be a focused introduction on Dark Matter, looking at its cosmological production mechanisms, its impact on astrophysics and cosmology, and its laboratory detection.

On the experimental side, the School will cover a range of techniques for probing weak electromagnetic fields, short distance forces, single photons, fundamental electric dipole moments, as well as atom interferometers and optomechanical sensors.

This course on quantum mechanics is divided in two parts:
 
The aim of the first part is to review the basis of quantum mechanics. The course aims to provide an overview of the perturbation theory to handle perturbations in quantum systems. Time evolution of quantum systems using the Schrodinger, Heisenberg and interaction pictures will be covered. Basics of quantum statistical mechanics for distinguishable particles, bosons, and fermions will be covered. A brief overview of density matrix approach and quantum systems interacting with the environment will be given.
 
The second part of the course is an introduction to scalar quantum field theory. The Feynman diagram technique for perturbation theory is developed and applied to the scattering of relativistic particles. Renormalization is briefly discussed.

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.
