New article in PRX

December 2019

Using thermal conductivity measurements, we investigated the issue of potential mobile spin excitations in a promising quantum spin liquid candidate and found no evidence that spinons contribute to heat transport. Despite measuring eight high-quality crystals, we were not able to reproduce the findings of a previous report on the same material that had found the opposite result.

Relève étoile Louis-Berlinguet Prize

October 2019

Congratulations to Gaël Grissonnanche, a post-doctoral student in Taillefer's group, for winning the Relève étoile Louis-Berlinguet. This award, granted but the Fonds de recherche- Nature et technologies (Québec), recognizes the excellence of research conducted by university-level students. Gaël received this award following her article Giant thermal Hall conductivity in the pseudogap phase of cuprate superconductors published in Nature in July 2019.

The international colloquium on quantum circuits and materials was held in Jouvence from October 2nd to 4th. All of the Taillefer group attended to discuss the latest advances in the field of quantum materials with our French collaborators.
Taking its roots in the decade-long collaborations between French researchers and members of the Physics Department of the Université de Sherbrooke, the LIA (International Associated Laboratory) on quantum circuits and materials was created in 2016 to strengthen research collaborations across the France-Canada axis.
