Quantum Field Theory I (2022/2023)
14 talksCollection Number C22036The 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 oneloop order.
Prerequisite: PSI Quantum Theory course or equivalently Graduate level Quantum Mechanics and QFT of scalar theory

Relativity (2022/2023)
14 talksCollection Number C22041This 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 Day of Discovery
10 talksCollection Number C22040Join 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.

Quantum Gravity Around the Corner
29 talksCollection Number C22029There 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 codimension2 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.

Quantum Theory (20222023)
14 talksCollection Number C22035This 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. 
Classical Physics (2022/2023)
14 talksCollection Number C22039This 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.

School on TableTop Experiments for Fundamental Physics
27 talksCollection Number C22030This School aims at bringing together graduate students and junior postdocs, both theorists and experimentalists, who are interested in proposing and realizing new tabletop 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 longrange 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.Territorial Land Acknowledgement

Cold Atom Molecule Interactions (CATMIN)
22 talksCollection Number C22028In the first edition of the meeting, CATMIN (Cold ATom Molecule INteractions) was a new satellite meeting of ICPEAC devoted to the study of atomic and molecular systems, where longrange interactions and the extreme properties of highly excited electrons produce new physics and lead to new technologies. CATMIN's objective is to strengthen the links between cold atom physics, molecular physics, chemistry and condensed matter physics, so that new concepts and breakthroughs can emerge. Ions, atoms and molecules are naturally made quantum systems that can be controlled with light and low frequency electromagnetic fields, thus lending themselves to precision investigations and use in quantum technologies. The second CATMIN conference will be held a few days before the ICAP, which is a major conference in AMO physics, with the idea that scientists can attend both meetings. The CATMIN meeting will be a twoday conference held at the Perimeter Institute in Waterloo, ON, centered on Rydbergatom physics, cold ion physics and the interplay between these experimental platforms. Rydberg atom physics is experiencing a renaissance due to the application of the exaggerated properties of highly excited atoms for quantum information and quantum simulation. Rydberg states can even be observed in solids which is a subject of increasing interest. Cold ions, similarly, are exciting for quantum simulation and computing, becoming one of the central platforms in the race to build a quantum computer. Many exciting developments are also in progress in the area of coldmolecules. Longrange interactions open up fields of research such as the photoassociation of cold atoms to form ultracold molecules, and the excitation of Rydberg molecules demonstrating novel kinds of molecular bonding. Strong longrange interactions in all the systems permit the investigation of the fewbody and manybody regimes, including the few to manybody transition. The conference aims to share the latest developments and results in these exciting fields among the various ICAP communities as well as the broader physics and chemistry communities. Overall, the conference can forward quantum science and the application of quantum science, which furthers these fields of research by concentrating interest to attract people and resources to the field.

Perimeter Institute will make every effort to host the conference as an inperson event. However, we reserve the right to change to an online program to align with changes in regulations due to the COVID19 pandemic.
