Strong Gravity research at Perimeter Institute is devoted to understanding both the theoretical and observational aspects of systems in which gravity is very strong (i.e., spacetime is highly curved or dynamical],. On one hand, this means studying extreme astrophysical systems, like black holes and neutron stars, as well as making and testing predictions for existing and forthcoming gravitational wave detectors, electromagnetic telescopes, and particle astrophysics experiments. On the other hand, it also includes a range of non-astrophysical topics, such as the instabilities of higher-dimensional black holes or the dynamics of strongly-coupled quantum field theories (via holography). The goal of strong gravity researcher is to test the validity of Einstein's theory of gravity, constrain proposed alternatives, understand the most extreme astrophysical systems, and investigate the ways in which highly curved or dynamical spacetimes are linked with a range of other problems in fundamental physics.

Relativity (Core), PHYS 604, November 12 - December 11, 2024
12 talks-Collection NumberC24037This course offers an introduction to general relativity (GR), focusing on the core principles of Einstein's theory of gravity. We will explore key topics such as the equivalence principle, some essential concepts in differential geometry, the Einstein-Hilbert action, and Einstein's field equations. Furthermore, we will examine practical applications of general relativity in understanding black holes, cosmology, and gravitational waves.

Gravitational Physics
13 talks-Collection NumberC24007The Gravitational Physics course takes your knowledge and practice of gravity to the next level. We start by recapping the essential elements of differential geometry, adding some new techniques to the toolbox, then apply some of these methods to learning about submanifolds, extra dimensions, and black hole thermodynamics. Towards the end of the course, we delve into the frontiers, with a sample of recent research topics.

Puzzles in the Quantum Gravity Landscape: viewpoints from different approaches
34 talks-Collection NumberC23033Unraveling the quantum nature of gravity is one of the most pressing problems of theoretical physics. Several ideas have been put forward and resulted in a number of theories of quantum gravity. While these theories have explored different facets of the “quantum gravity landscape”, all viable approaches should ultimately make contact with observations, and answer exciting questions in cosmology and black-hole physics.
Sharing knowledge, exchanging ideas, and building a dictionary between different theories are crucial steps toward answering these questions, efficiently contrasting different theories, and ultimately reaching a deeper understanding of our Universe.
This conference will contribute to these goals by bringing together leading experts in different approaches to quantum gravity, gravitational effective field theory, black-hole physics, and cosmology. We will focus on specific puzzles in quantum gravity and their resolutions within different approaches. The conference will be highly interactive, with plenty of time to discuss common problems, understand the big picture, and develop novel connections between fields.Registration: Registration is now open, and both in-person and virtual participation is welcome. Online participants will be able to interact on an equal footing in question sessions and discussions. In-person attendance is limited and will be approved on a first-come, first-served basis. Talks are by invitation only, but in-person participants are encouraged to apply to present a poster.

Quantum Simulators of Fundamental Physics
23 talks-Collection NumberC23019This meeting will bring together researchers from the quantum technology, atomic physics, and fundamental physics communities to discuss how quantum simulation can be used to gain new insight into the physics of black holes and the early Universe. The core program of the workshop is intended to deepen collaboration between the UK-based Quantum Simulators for Fundamental Physics (QSimFP; https://www.qsimfp.org) consortium and researchers at Perimeter Institute and neighbouring institutions. The week-long conference will consist of broadly-accessible talks on work within the consortium and work within the broader community of researchers interested in quantum simulation, as well as a poster session and ample time for discussion and collaboration

Path to Kilohertz Gravitational-Wave Astronomy
17 talks-Collection NumberC18014We are entering an exponentially growing phase of gravitational-wave (GW) astronomy excitingly represented by the Nobel Prize in Physics last year - only two years after the first detection. The successful multi-messenger detection of binary neutron star merger in last August has triggered increasing interests to probe the neutron star post-merger gravitational radiations as they will give more decisive and informative description of the post-merger object itself and the GW/electromagnetic emission mechanism. As the post-merger GWs mainly lie in the 1kHz-4kHz band it becomes necessary and important to think about possible third-generation GW detectors that are primarily sensitive to the high frequency band. In this workshop we shall focus on possible science case and detector configuration for kHz high-frequency detectors. We will have several invited talks while leaving more time for free discussions. We hope this workshop can serve as a seed for much broader discussions in the GW astronomy community and help promote high frequency detectors as one of the development directions of third-generation GW detectors.
