Theory + AI Symposium
As Perimeter enters its 25th year, we invite you to imagine what theoretical physics research will look like 25 years from now. On April 7 and 8, Perimeter will be hosting a symposium with speakers and panel discussions focusing on the promise of AI to accelerate progress in theoretical physics. These talks will address the possibilities and challenges associated with AI ‘doing science.’ The event will bring together physicists, engineers, AI researchers, and entrepreneurs to collect different perspectives on what the future of theoretical physics will look like, the engineering challenges we should expect along the way, what tools and collaborations will be needed to help get us there, and what exciting steps are already underway.Confirmed Speakers:

Quantum Matter (Elective), PHYS 777, March 31 - May 2, 2025
This course will cover quantum phases of matter, with a focus on long-range entangled states, topological states, and quantum criticality.

Cosmology (Elective), PHYS 621, March 31 - May 2, 2025
This course in Cosmology provides a theoretical overview of the standard cosmological model. Key topics include the FRW metric and the homogeneous universe, the thermal history of the universe (with an emphasis on the hot Big Bang and equilibrium thermodynamics), inflation and scalar field dynamics, along with selected aspects of cosmological perturbation theory (time permitting).

AdS/CFT (Elective), PHYS 777, March 31 - May 2, 2025
We will cover the basics of the gauge/gravity duality, including some of the following aspects: holographic fluids, applications to condensed matter systems, entanglement entropy, and recent advances in understanding the black hole information paradox.

Quantum Gravity (Elective), PHYS 644, February 24 - March 28, 2025
The main goal of this course is to show in which ways General Relativity (GR) is similar, and especially in which ways it is different, from other gauge theories. The largest component of the course is dedicated to studying the specific symmetry structure of GR and how it intimately relates to its dynamics. To do so, we will introduce a host of concepts and techniques, broadly (and loosely) known under the name of “Covariant Phase Space Method”. This provides a different perspective on GR’s physics, a perspective in which phase space, rather than spacetime, is front and center. Along the way we will take a few detours: we will explore (parts of) the historical debate on whether gravity should be quantized at all, discuss how to think of time evolution when there is no absolute time, and go through Wald’s proposal of black hole entropy as a Noether charge. The intended outcome of the course is to provide a new perspective on GR which, hopefully, will inform you on why it is much harder to quantize than other theories – especially from a non-perturbative perspective. In this sense the course always keeps an eye on Quantum Gravity, even though there will be very little “quantum” in it. It is also a course that does not hinge on any specific approach to the quantization of gravity. Also, it is worth noting that the covariant phase space techniques are broadly used in the current literature on the black hole information paradox, soft symmetries, and holography, and is therefore a useful tool to learn if you are interested in any of these topics.

Causal Inference (Elective), PHYS 777, March 31 - May 2, 2025
Can the effectiveness of a medical treatment be determined without the expense of a randomized controlled trial? Can the impact of a new policy be disentangled from other factors that happen to vary at the same time? Questions such as these are the purview of the field of causal inference, a general-purpose science of cause and effect, applicable in domains ranging from epidemiology to economics. Researchers in this field seek in particular to find techniques for extracting causal conclusions from statistical data. Meanwhile, one of the most significant results in the foundations of quantum theory—Bell’s theorem—can also be understood as an attempt to disentangle correlation and causation. Recently, it has been recognized that Bell’s result is an early foray into the field of causal inference and that the insights derived from almost 60 years of research on his theorem can supplement and improve upon state-of-the-art causal inference techniques. In the other direction, the conceptual framework developed by causal inference researchers provides a fruitful new perspective on what could possibly count as a satisfactory causal explanation of the quantum correlations observed in Bell experiments. Efforts to elaborate upon these connections have led to an exciting flow of techniques and insights across the disciplinary divide. This course will explore what is happening at the intersection of these two fields.

Magnetic Fields Around Compact Objects Workshop
In the vicinity of neutron stars and black holes, where spacetime is strongly curved, magnetic fields can power many of the violent phenomena that we observe across the entire electromagnetic spectrum, from accretion and jet launching, to magnetar flares and pulsar emission. In the last decades, our theoretical understanding of the role of magnetic fields in these extreme environments has greatly improved through numerical simulations of magnetohydrodynamical fluids and charged kinetic particles; however, many open and important questions remain. Our observational capabilities and computational resources will keep growing dramatically in the next few years, allowing us to explore high-energy astrophysics in unprecedented regimes. Improving our knowledge of how magnetic fields, matter, and gravity interact with each other is a crucial piece in the new era of multimessenger astrophysics.This workshop will gather experts from a wide range of disciplines within physics and astrophysics to present state-of-the-art advances in theoretical models of magnetic fields and high-energy plasma in different contexts, from neutron star mergers to supermassive black holes, and from micro scales to macro scales.This workshop is sponsored in part by the Canadian Institute for Theoretical Astrophysics (CITA).

Emmy Noether Workshop: Quantum Space Time
Constructing a theory of quantum gravity, and with it a notion of quantum spacetime is one of the biggest challenges faced by modern theoretical physics. This workshop will bring together researchers from a wide range of viewpoints and give them an opportunity to exchange ideas and gain new insights.
The workshop is supported by the Simons Foundation.
