Bianca Dittrich wins CAP-CRM Prize
The 2024 CAP-CRM Prize in Theoretical and Mathematical Physics was awarded today to Perimeter Institute Faculty Chair Bianca Dittrich.
The award commends Dittrich for her “important contribution to our understanding of the problem of observables in quantum gravity, and for her advancement of spin foam approaches to quantum gravity.”
“Without a doubt, Bianca Dittrich is an incredibly deserving recipient of this year’s CAP-CRM Prize,” said Perimeter Institute Director Robert Myers. “She is a brilliant scientist and an international leader in quantum gravity. With acute technical and mathematical expertise and deep creativity, she has opened multiple new perspectives in our fundamental understanding of spacetime.”
Quantum gravity research aims to reconcile quantum field theory with Einstein’s theory of gravity. Both are highly successful theories fundamental to our understanding of the universe, but they remain incompatible. Uniting them is one of the grand challenges of modern physics.
Dittrich recently broke through a decades-long impasse in this area by demonstrating an entirely novel construction of quantum geometry, one which makes it possible to extract information about long-range physics.
Before this breakthrough, only one such construction was known, and it produced degenerate spacetimes that made long-range physics inaccessible, and was therefore ill-equipped to confirm whether the quantized geometry could replicate the predictions of general relativity. Dittrich’s new quantum geometry construction produces non-degenerate and nearly flat spacetimes similar to the observed universe, which has enabled rapid progress in this area.
Similarly revolutionary is Dittrich’s work developing “effective spin foams”, a tool that enables tests of quantum gravity models without the need for supercomputers, making them computationally feasible for the first time.
“I am deeply honoured, very happy, and thankful for receiving this prize,” said Dittrich. “I want to thank the CAP and the CRM for this recognition, as well as my remarkable colleagues, students, and collaborators, with whom it has been a joy to work alongside.”
The CAP-CRM Prize is jointly awarded by the Canadian Association of Physicists and the Centre de recherches mathématiques.
À propos de l’IP
L'Institut Périmètre est le plus grand centre de recherche en physique théorique au monde. Fondé en 1999, cet institut indépendant vise à favoriser les percées dans la compréhension fondamentale de notre univers, des plus infimes particules au cosmos tout entier. Les recherches effectuées à l’Institut Périmètre reposent sur l'idée que la science fondamentale fait progresser le savoir humain et catalyse l'innovation, et que la physique théorique d'aujourd'hui est la technologie de demain. Situé dans la région de Waterloo, cet établissement sans but lucratif met de l'avant un partenariat public-privé unique en son genre avec entre autres les gouvernements de l'Ontario et du Canada. Il facilite la recherche de pointe, forme la prochaine génération de pionniers de la science et communique le pouvoir de la physique grâce à des programmes primés d'éducation et de vulgarisation.
