This meeting will focus on recent developments exploring emergent electronic, magnetic, and topological phenomena in two-dimensional synthetic structures of quantum materials. The strong interplay between electronic correlations, spin orbit coupling, crystal structure, symmetry, and topology often leads to various collective phenomena in bulk crystals. With reduced dimensionality, the frustrated coupling across 2D interfaces or enhanced interlayer interactions between different quantum materials can lead to new electronic band structures (e.g., flat bands) and to host emergent behaviour which are unattainable otherwise in the constituent bulk systems.This workshop will bring together physicists and materials scientists interested in artificially engineered heterostructures including oxide interfaces, oxide heterostructures, twisted van der Waals materials, twisted cuprates, and other novel moire or layered materials. The participants will have complementary experimental and theoretical...

Recent years have seen a flood of new data, from gravitational wave observations of merging black holes and neutron stars to precision probes of cosmology, which allow for unprecedented tests of our understanding of gravity. Going hand-in-hand with this, there has been significant recent progress on the theoretical side in terms of formulating modified theories of gravity, and using them to make detailed predictions, including in the nonlinear and dynamical regime, which can be confronted with the observations. 

We are excited to announce a landmark conference that plans to delve into the forefront of research on modified theories of gravity and brings together leading experts from different disciplines including observational astrophysicists, numerical relativists, cosmologists and mathematical physicists to explore the present status of modified theories of gravity and envision their future theoretical development and implications for observations.

This conference is also timed to coincide with the 50th anniversary of pioneering work in this area carried out by Gregory Horndeski in the Waterloo Mathematical Physics Community. Hosted jointly by Perimeter Institute and the University of Waterloo, this conference will serve as a forum for researchers from different disciplines to exchange ideas at the cutting
edge of gravitational physics.

Our world is changing! Natural habitats are being degraded at an unprecedented rate. In addition to known threats to biodiversity, this habitat change also paves the way for emerging infections that can cause serious public health concerns. Have you ever wondered how change in biodiversity is linked to human health and well-being? And how biodiversity changes can alter natural transmission cycles of pathogens? If so, this course is for you. Disease ecology integrates theories from many scientific disciplines (e.g., ecology, evolution, mathematics, etc.) to understand how ecological and environmental processes influence the distribution, prevalence, and dynamics of diseases in animal populations. This field has gained significant importance recently, especially in light of global health challenges (e.g., COVID-19, Ebola, etc.). By studying disease ecology, we can gain valuable insights into how diseases emerge, spread, and impact ecosystems and human societies. Our goal in this course i...

The Perimeter Scholars International (PSI) Master's program is offered in collaboration by Perimeter Institute and the University of Waterloo.

The school is designed to encourage women to take up physics as a career. The sessions will be centered on some simple physics experiments, conducted by the students, or as demonstrations. The subsequent discussion will focus on theoretical aspects motivated by the experiments and explore physical ideas and theory in an open ended manner, so as to bring out the excitement and interconnectedness of the subject. We will also have problem solving sessions and special lectures by invited speakers. Participants will be required to stay on the ICTS campus and attend the entire school in order to maximally benefit from the experience.Eligibility criteria: The school is open to women studying for a bachelor’s degree/Integrated Masters degree with physics as a subject, and are entering their second or third year.  This is a residential school and the selected participants will be fully supported. No registration fee. 

The dialogue between quantum information and quantum matter has fostered notable progress in both fields. Quantum information science has revolutionized our understanding of the structure of quantum many-body systems and novel forms of out-of-equilibrium quantum dynamics. The advances of quantum matter have provided novel paradigms and platforms for quantum information processing.
This conference aims to bring together leading experts at the intersections of quantum information and quantum matter. Key topics include: (i) quantum error correction, (ii) quantum dynamics, and (iii) quantum simulation.

The Earth’s climate is dictated by atmospheric and oceanic dynamics, spanning over a wide range of temporal and spatial scales that undergo multi-scale interactions resulting in energy transfers across a multitude of scales. The energy transfers across these multi-scale regimes are key to the understanding of the energy cycle, but their quantification remains poorly constrained. Physical processes such as turbulent mixing and instabilities are difficult to observe or resolve in the numerical models and are often parametrized. Consequently, the question of energy-consistent closure in ocean and climate models, which heavily rely on parametrizations, remains open and challenging to address. To address these questions, a combination of analytical theories, numerical models, and observational measurements is necessary to advance our understanding of oceanic and atmospheric dynamics.The meeting spans two weeks addressing multi-scale and multi-physics topics in geophysical fluid dynamics inc...

The dynamic field of quantum physics and artificial intelligence is expanding across both academic and industrial landscapes. This mini-course offers an introduction to computational techniques currently utilized in the quantum sector, highlighting non-academic career paths for individuals interested in quantum physics and machine learning. The program features two lecture series: one on generative modeling - covering topics (such as restricted Boltzmann machines, recurrent neural networks, and transformers) - and the other on quantum machine learning algorithms. Participants will also benefit from practical coding tutorials, networking opportunities, and related events about the landscape of Quantum and AI.

Join us for a one-day hybrid symposium as we delve into the groundbreaking discoveries from the Dark Energy Spectroscopic Instrument (DESI) and the extended ROentgen Survey with an Imaging Telescope Array (eROSITA). This first-of-its-kind-in-India event will have eminent scientists from these large collaborations, talking about these surveys, offering an opportunity to explore the frontiers of research in cosmology and large-scale structures of the Universe. The symposium is aimed at looking at the latest revelation concerning the mysteries of dark energy, new constraints of neutrinos, the latest map of the large-scale structure of the universe, and unveiling an all-sky catalogue of the largest virialized objects in our Universe shining brightly in X-Rays. These two latest and largest surveys bring unique insights into the formation and evolution of galaxies, the distribution of matter on cosmic scales, and the elusive nature of dark matter.Rarely in the history of astroparticle physic...

Understanding phenotypic variation in terms of the underlying genetic variation is one of the central problems in biological evolution. During the last decade, valuable insights into the genetic architecture of phenotypic traits have been obtained and it is found that many phenotypic traits ranging from crop yield and human height to complex diseases are polygenic, that is, they are influenced by a large number of genetic variants. Despite this evidence, evolutionary biology continues to be dominated by two extreme views of adaptive dynamics where adaptation occurs either via large changes at a few genetic loci or infinitesimal changes at a very large number of them. The aim of this program is to integrate these two seemingly disparate ideas into a single framework and extend their ambit to include other modes of adaptation, and address how one can describe other scenarios quantitatively and relate them to empirical data.The program will feature pedagogical lectures, research seminars ...
