Neil Turok<\/h4>\n

Higgs Chair of Theoretical Physics, University of Edinburgh and Roger Penrose Distinguished Visiting Chair, Perimeter Institute for Theoretical Physics<\/strong><\/p>\n

Neil\u00a0is the inaugural Higgs Chair of Theoretical Physics at Edinburgh. He was born in South Africa to activist parents in the anti-apartheid movement. After studies in Cambridge and London and appointments in California and Chicago, he was Professor of Physics at Princeton, Chair of Mathematical Physics at Cambridge and Director of the Perimeter Institute for Theoretical Physics in Canada.<\/p>\n

Neil develops and tests theories of the universe and its basic laws, from the big bang to the far future. Many of his team\u2019s predictions have been confirmed, including correlations between the distribution of galaxies and the cosmic microwave background radiation. He has proposed a new paradigm for cosmology, connecting particles and forces to the dark matter, dark energy and primordial density variations. Its predictions will be tested in the coming decade.<\/p>\n

In 2003, Neil founded the\u00a0African Institute for Mathematical Sciences (AIMS), now Africa\u2019s largest centre for postgraduate training and research in the mathematical sciences. Currently, AIMS operates 6 centres of excellence, in South Africa, Senegal, Ghana, Cameroon and Rwanda. AIMS has over 3,500 Master\u2019s and PhD alumni. In the coming decade, AIMS plans to open 4 additional centres of excellence and to graduate 10,000 students at Master\u2019s level and above.<\/p>\n

For his research and for founding AIMS, Neil was awarded a\u00a0TED\u00a0Prize. He holds honorary doctorates from nine universities. In 2012, his book\u00a0The Universe Within: From Quantum to Cosmos\u00a0<\/em>won Canada\u2019s top prize for popular science writing. In 2016, he was awarded the John Torrence Tate award of the American Institute of Physics for international leadership in physics.\u00a0He is an Honorary Fellow of the UK Institute of Physics and a Fellow of the Royal Society of Canada.[\/vc_column_text][vc_column_text css=””]A Simpler Cosmology<\/strong><\/p>\n

Observations of the universe on the largest and smallest accessible scales have revealed surprising simplicity.\u00a0In contrast, the most popular theoretical frameworks predicted a slew of new particles, forces and dimensions on the tiniest, subatomic scales, and a chaotic multiverse on the greatest. The observations should make us reconsider our assumptions. Might there be better explanations for the basic properties of the universe? I\u2019ll outline a new, simpler unified paradigm, based on the known laws of physics and CPT symmetry, which explains (i) the large-scale geometry of the universe and the primordial density perturbations, without inflation, (ii) the dark matter as a right handed neutrino, without any other BSM particle, (iii) why there are three generations of elementary particles, without strings. The new picture provides clues about quantum gravity,\u00a0the big bang\u00a0and the arrow of time as well as a potential resolution of the gauge-gravity hierarchy puzzle.<\/p>\n

John Donohue | University of Waterloo<\/h4>\n

Lundi 22 juin, de 9 h \u00e0 9 h 45<\/strong><\/p>\n

Dr. John Donohue is an experimental physicist and outreach scientist with the Institute for Quantum Computing (IQC) at the University of Waterloo. His work focuses on teaching and communicating about advances in quantum science and technology, including through hands-on activities and demonstrations and programs like the Quantum School for Young Students (QSYS) and Quantum for Educators (QEd). His research work focuses on experimental quantum information in photonic systems. His work has been recognized by funding from the American Physical Society and Innovation, Science, and Economic Development Canada, and he was invited to speak on quantum education efforts at the opening ceremony of the 2025 International Year of Quantum Science & Technology at UNESCO headquarters. He also served as the Chair of the Division of Physics Education for the Canadian Association of Physicists from 2023-2025.[\/vc_column_text][vc_column_text css=””]Quantum for Educators and Young Students<\/strong><\/p>\n

The explosion of public interest in quantum information technologies has provided an opportunity to interest more students in the ideas and applications of quantum mechanics. As research programs and institutes have grown in Canada, so have efforts to reach new communities and teach concepts in new and tactile ways. To allow high-school students to engage with quantum information science on a broad scale, it is essential to provide educators with the resources needed to understand and effectively communicate the topic to students. We have run the Quantum for Educators (QEd) workshop for ten years to address this need, providing hands-on activities and lesson plans designed for the classroom. To ensure broad and equitable access to introductory QIS education, such activities should be low-cost, easy to replicate, and intuitive, as well as connect to material present in the curriculum. In this talk, we will outline the QEd workshop and its approach to topics including quantum communication, quantum algorithms, and uncertainty, sharing survey feedback and lessons-learned from many iterations. We will also explore how enrichment programs can be developed for keen high-school students both in-person and virtually, as in the Quantum School for Young Students (QSYS) summer school which has run for 18 years, and how these connect to undergraduate-level programming like the 16-year-running Undergraduate School on Experimental Quantum Information Processing (USEQIP).<\/p>\n

\n<\/strong><\/h4>\n

Mardi 23 juin, de 9 h \u00e0 9 h 45<\/strong><\/p>\n

Normand Mousseau is a professor of physics at l\u2019Universit\u00e9 de Montr\u00e9al, a \u00a0scientific director of the Institut de l’\u00e9nergie Trottier (IET) and co-director of the Energy Modelling Hub. His work, reported in more than 240 scientific articles, focuses on the atomistic kinetics of complex materials and biomolecules. He has also been working on issues relating to energy and natural resources for more than fifteen years. He is the author of several books on the subject. He is a co-author of numerous reports associated with the energy transition, including the IET Canada Energy Outlook series, which released its third edition in 2024-25.[\/vc_column_text][vc_column_text css=””]How can physicists contribute to the climate challenge?<\/strong>
\nGlobal warming is a central issue for our civilization. While it has broad impact, it is at its core simply a matter of energy balance. Given its fundamental nature, global warming has attracted the attention of many physicists over the years. This includes climatologists, of course, many of whom hold a physics degree, and whose main work focuses on describing and understanding the impact of greenhouse gases on the evolution of the climate. It also includes physicists interested in \u00a0developing critical fundamental and applied solutions to move away from a fossil-based society as well as those interested in planning the transformation of our energy system or in.<\/p>\n

Yet, even though energy transition involves a lot of technology and science concepts, to contribute to such a transversal transformation, physicists must expand their traditional training: unlike physical systems, social transformations are not deterministic, requiring scenario-based thinking largely foreign to physics training.<\/p>\n

Building on my own experience working on the energy transition, I’ll present examples of how physicists do contribute to this challenge by building on the fundamental scientific knowledge and problem-solving tools that are part of our physics training and how we can use those skills for her society-wide problems.<\/p>\n

Saniya Heeba | Carleton University\u00a0<\/strong><\/h4>\n

Jeudi 25 juin, de 9 h \u00e0 9 h 45<\/strong><\/p>\n

I am an IPP Connect Fellow based at Carleton University in Ottawa, Canada. I completed the first two years of my IPP fellowship at McGill University, Canada, where I previously held a Trottier Space Institute Postdoctoral Fellowship. I obtained my Ph.D. in Physics from RWTH Aachen University in Germany.<\/p>\n

My research focuses on analyzing the behaviour of Dark Matter (DM) across different energies and environments and connecting it to detectable experimental signatures. I am particularly interested in understanding how ambient environments, such as primordial, stellar or interstellar plasmas, fundamentally impact DM observables. I also often create art for my research projects, which is available in the form of little easter eggs on arXiv.[\/vc_column_text][vc_column_text css=””]The Universe as a Dark Matter Laboratory<\/strong><\/p>\n

One of the fundamental unanswered questions about the universe is the nature of Dark Matter (DM) \u2014 a mysterious, invisible form of matter that accounts for 80% of the universe\u2019s total matter budget. Despite its overwhelming abundance in the Universe, the microphysical properties of DM remain poorly constrained owing to its extremely weak interactions with normal matter. This has resulted in a sprawling DM theory space with several models, potential observable signatures and search
\nstrategies.<\/p>\n

In this talk, I will provide a particle physics perspective on approaching the DM question and discuss the many ways it intersects with astrophysics and cosmology. I will demonstrate how to use the universe as a DM laboratory, with an emphasis on using different energy scales and ambient environments as a test bed for DM physics. Through the course of the talk, I will trace out the possible histories of DM, discuss its impact on astrophysical observables, and make contact with the expansive terrestrial DM experimental program.<\/p>\n

A recurring theme in contemporary quantum materials physics is the understanding of new quantum magnets which display novel disordered ground states due to geometric frustration, quantum fluctuations or both. Neutron scattering, arguably the most powerful probe of magnetism in solids, has a proud Canadian history. Modern neutron sources and instrumentation have given us unprecedented capabilities to study weaker, more diffuse signals in new quantum materials. I will review how these developments came to be, and how modern neutron techniques are well suited for my group\u2019s focus: elucidating quantum disordered ground states and their exotic excitations in new materials.<\/p>\n

Laur\u00e9at de la M\u00e9daille Herzberg de l’ACP 2026[\/vc_column_text][vc_column_text css=””]What is an antiferromagnet, really?<\/strong><\/p>\n

Magnetically ordered materials are often divided into two broad classes: ferromagnets, which have a net magnetization, and antiferromagnets, which do not. However, recent work has shown that, in the non-relativistic limit, this classification is incomplete. It overlooks a qualitatively different type of compensated collinear order now called \u201caltermagnetism.\u201d Like conventional antiferromagnets, altermagnets have vanishing net magnetization. Unlike conventional antiferromagnets, their crystal and spin symmetries allow momentum-dependent spin splitting, chiral magnetic excitations, and response functions more commonly associated with ferromagnets. By combining distinct features of ferromagnets and antiferromagnets, altermagnets are promising for applications in spintronics, where electron spin is used to process and store information efficiently.<\/p>\n

In this talk I will survey the emerging field of altermagnetism and describe my contributions to the effort to understand this new class of magnetic systems. I will focus on the symmetry principles that distinguish altermagnets from conventional ferromagnets and antiferromagnets, the phenomenology that follows from those symmetries, and recent experiments aimed at revealing altermagnetic signatures in real materials.<\/p>\n

Interacting electrons in quantum materials can give rise to new emergent properties that may be harnessed in future quantum technologies. One example is the quantum spin liquid, an elusive state of matter that can host fractionalized excitations with potential applications in quantum computing. Neutron and X-ray scattering play an essential role in probing such excitations in quantum materials. In particular, a spectroscopy technique called Resonant Inelastic X-ray Scattering (RIXS) has proven crucial for studying magnetic properties in materials with strong spin\u2013orbit coupling, such as iridates and ruthenates. These materials have attracted significant interest because they can host bond-dependent magnetic interactions, known as Kitaev interactions, which are a key ingredient for realizing a Kitaev quantum spin liquid. Among candidate materials, alpha-RuCl3 is considered especially promising. In this talk, I will discuss our investigation of its magnetic, electronic, and structural properties using X-ray and neutron scattering techniques.<\/p>\n

There is overwhelming and increasingly precise gravitational evidence for dark matter, however, no experiment has yet achieved an unambiguous detection at the particle level. Current searches are now entering a qualitatively new regime in detector scale, sensitivity and detection strategy. In this talk I shall focus in particular on the superheated liquid technique, pioneered by the PICASSO experiment at SNOLAB, and subsequently further developed by PICO, now a world leading experiment in the spin-dependent WIMP interaction sector. I will also discuss recent efforts to probe the dark sector in nuclear transitions, with particular emphasis on work by the Montreal X17 collaboration.<\/p>\n
