The aim of the first part is to present a brief overview of selected topics in quantum theory. Schrodinger, Heisenberg and Interaction picture is discussed and applied to study time evolution. Density matrix and Feynman path integral are introduced. The second part of the course derives the Feynman rules for scalar quantum field theory and introduces renormalization.

The study of zero mean curvature surfaces in $\mathbb{R}^3$ (minimal surfaces) has witnessed significant progress since its initiation over 200 years ago. However, the topics of maximal surfaces (ZMC surfaces) in the Lorentz-Minkowski space and ZMC surfaces in hyperbolic spaces,  are relatively recent. The proposed meeting on Zero Mean Curvature surfaces aims to bring together leading experts in the areas  to discuss a wide range of topics- new challenges, problem-solving methodologies. Early-career researchers will have the opportunity to engage with the most significant and promising problems within these domains. This discussion meeting is intended to inspire faculty, students, and postdocs to delve into this vibrant and evolving field of research.During the five-day discussion meeting, the final day will be reserved for open discussions to encourage potential collaborations. There will be mini-courses by subject experts of introductory nature for younger researchers, who are  not e...

In recent years, the AdS/CFT correspondence has led to a paradigm shift in the quest for a theory of quantum gravity. In this new approach, spacetime and gravity are viewed not as fundamental, but as emergent descriptions of the dynamics of quantum information in an underlying, microscopic quantum system. The resulting theory has led to a novel confluence between two different subjects, namely general relativity and quantum information theory. This confluence has enriched both the subjects. On the one hand, tools from quantum information theory such as quantum error correction have led to ground-breaking progress on long-standing problems in quantum gravity such as the black hole information paradox. On the other hand, black hole physics has led to fundamental insights on information scrambling in chaotic quantum systems.Quantum information theory has also provided a new window into the rich world of quantum field theories and many-body dynamics. Fundamental inequalities governing the ...

This meeting focuses on the recent advances taking place in our understanding of kagome metals with a particular emphasis on following sub-fields:1. Intertwined Density-wave and Superconducting order2. Leading and subleading nematic fluctuations3. Itinerant vs Localized Magnetism and Electronic instabilitiesThe subtle interdependence of Fermiology, interactions, and a multi-sublattice unit cell lies at the heart of the intriguing scenario of correlated electrons in a kagome metal. While typical metallic parent states feature Fermi surface instabilities dictated by screened Coulomb interactions recast by a Hubbard coupling U , the sublattice interference in kagome metals naturally render longer-randed coupling pivotal in understanding the effective interactions of electronic states at and around the Fermi level. Together with a likewise intriguing characteristic phonon spectrum and possibly significant electron-phonon coupling, kagome metals present themselves as a particularly rich cor...

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.

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...

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.
