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

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.

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.
