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...
