50 Years of Horndeski Gravity: Exploring Modified Gravity
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.

Engineered 2D Quantum Materials
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...

Emerging infectious diseases: ecology and evolution
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...

Summer School on Gravitational-Wave Astronomy
Now that observation of gravitational waves (GWs) from coalescing compact binary mergers has become routine, it is intriguing to consider other potential sources of GWs. With the upcoming observing runs of LIGO, Virgo and KAGRA, there is a possibility that such signals could be detected. This year’s ICTS GW Summer School will focus on the sources and searches for continuous GWs. This includes continuous GWs from rapidly spinning neutron stars in our own galaxy as well as exotic sources such as axion clouds around black holes. Courses: The astrophysics of neutron stars and binaries (Dipankar Bhattacharya, Ashoka University, India) Ultralight boson clouds around black holes (Nils Siemonsen, Princeton University, USA) Rapidly spinning neutron stars and emission mechanisms (Keith Riles, University of Michigan, USA) Searches for continuous GWs: Methods and results (Alicia M Sintes, University of the Balearic Islands, Spain) Eligibility criteria: The school is primarily meant for gradu...

Summer School for Women in Physics 2024
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.
