The Wilson-Wilkins theory center (OSU), the University of Toronto, and the International Center for Theoretical Sciences (ICTS) Bangalore, are jointly organizing the “Targeted Questions” web meeting series. These will be short 1-day meetings on specific questions tied to quantum materials theory and experiments. The aim is to have a few talks summarizing our understanding of specific materials (or class of materials), followed by a panel discussion to highlight important open issues, and encourage collaboration and progress. Our aim is to be mindful of diversity and inclusivity of researchers across all time zones. Meeting 1 (September 22, 2022 ) :  Quantum magnetism in Cr-halidesET -  0900 - 1230 Focus:What is the microscopic Hamiltonian for CrI3? Role of ligand spin-orbit coupling?Is the Kitaev coupling important? What is its sign and magnitude? Can we use high resolution neutron scattering to probe the Kitaev exchange at large B?Are there ways to tune the Kitaev coupling?How can we ...

Complex systems are seen across various branches of science; examples include climatic systems, financial markets, systems biology, and ecosystems. Many new techniques have emerged for understanding the dynamics of complex systems and predicting their long-term behavior, which are often obscured by apparent randomness and disorder. Nevertheless, these systems can undergo abrupt, large, and often irreversible changes to the system's state that have wide-ranging implications. When a dynamical system is tipped to a contrasting state in a relatively short period under the influence of small stochastic perturbations; this phenomenon is called a critical-transition or tipping. In the last two decades there are significant developments in the studies of tipping. This workshop will cover all the three major types of tipping; B-tipping, N-tipping and R-tipping, and will also discuss the recent advances on tipping point research including the application of machine learning.The meeting aims to b...

Frustration, i.e., the intertwining of competing physical state formation tendencies, is a ubiquitous theme in contemporary condensed matter physics. While certain domains such as frustrated magnetism are more established than others, the perspective of frustration applied to correlated electron systems promises to deepen and elevate understanding of a broad set of principles such as competing orders, quantum state entanglement, and criticality. While a Mott state is often rather canonically reconciled from the viewpoint of frustration, itinerant electron systems can likewise exhibit similar features that are intimately connected to the symmetry and topology of a metal or band insulator. Our ICTS workshop “Frustrated Metals and Insulators” aims at bringing together a diverse community of condensed matter researchers to push the state of the art and extend understanding towards a synergetic foundation of frustration phenomena in metals as well as insulators. The workshop intends to faci...

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 the physics and discussing it in a lively atmosphere full of questions.

Perimeter Institute will make every effort to host the conference as an in-person event.  However, we reserve the right to change to an online program to align with changes in regulations due to the COVID-19 pandemic.

Territorial Land Acknowledgement

Perimeter Institute acknowledges that it is situated on the traditional territory of the Anishinaabe, Haudenosaunee, and Neutral peoples.

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. 

We thank the Anishinaabe, Haudenosaunee, and Neutral peoples for hosting us on their land.

The second edition of the program "Nonperturbative and Numerical Approaches to Quantum Gravity, String Theory, and Holography" aims to bring together theorists working in the areas of lattice field theory, string theory, and quantum gravity to discuss the state of the art nonperturbative methods and numerical approaches to tackle current and relevant problems in string theory and holography.The program via its strong pedagogical component aims also to build and grow a community of theorists in India who would contribute to work connecting nonperturbative field theories, string theory, supersymmetric/superconformal field theories, quantum black holes, gravity, and holography.The content of this program can be broadly divided into four topics:Lattice Supersymmetric Field Theories: Recent developments in realizing N=4 supersymmetry on the lattice (including ideas on regulating flat directions, static quark potential, anomalous dimension of Konishi operator), N=1 supersymmetry on the latti...
