Classical and Quantum Chaos 2021/2022
Chaos, popularly known as the butterfly effect, is a ubiquitous phenomenon that renders a system's evolution unpredictable due to extreme sensitivity to initial conditions. Within the context of classical physics, it often occurs in nonintegrable Hamiltonian systems and is characterized by positive Lyapunov exponents. On the other hand, the notion of nonintegrability and chaos in quantum physics is still not wellunderstood and is an area of active research. Several signatures have been studied in the literature to identify quantum chaos but all of them fall short in some way or the other. In this course, we will first discuss the notions of classical integrability, and classical chaos and its characterization with Lyapunov exponents. Then, we will discuss a few wellstudied signatures of quantum chaos and the subtleties associated with them.

Postdoc Welcome 2021
As COVID19 continues to impose gathering restrictions, the “Postdoc Welcome 2021” will continue as a virtual event this year and will be hosted on Thursday, October 28 and Friday, October 29. 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.
There will be two 60minute sessions:
Thursday, October 28: 12:00 – 1:00 pm
Friday, October 29: 11:30 – 12:30 pmAll PI Residents are encouraged to attend. Registration will remain open until 9:00 am on Thursday, October 28.
Please register for the Postdoc Welcome via the event website: https://events.perimeterinstitute.ca/event/9/overview

Octonions and the Standard Model
Over the years, various researchers have suggested connections between the octonions and the standard model of particle physics. The past few years, in particular, have been marked by an upsurge of activity on this subject, stimulated by the recent observation that the standard model gauge group and fermion representation can be elegantly characterized in terms of the octonions. This workshop, which will be the first ever on this topic, is intended to bring this new community together in an attempt to better understand these ideas, establish a common language, and stimulate further progress.
The workshop will consist of an hourlong talk every Monday at noon (EST), with the first talk on Monday February 8, and the final talk on Monday May 17.
