Electrons with Planckian scattering obey standard orbital motion in a magnetic field

December 2022

In strange metals, electrons undergo Planckian dissipation. The temperature dependence of this strong scattering is anomalous (linear rather than quadratic resistivity). The Taillefer group has shown that the magnetic field dependence of this scattering is normal.

Quantum technology: a new France-Canada network

November 2022

An international network in quantum science and technology, set in motion by the CNRS, will officially be launched as of January 1, 2023. 16 French and Canadian universities will be part of this network, including the University of Sherbrooke, and Louis Taillefer will be a member of the executive committee.

Cifar Quantum Materials Program Meeting

May 2022

A few member of the Taillefer group attended the in-person Toronto 2022 Cifar Meeting. They had a great experience with lots of interresting discussion!

This program is working towards bringing on the Quantum Age. It explores the fundamental science behind quantum matter — the resource for the quantum technologies that will define the 21st century. These technologies could include room-temperature superconductors that would carry electricity without any loss and revolutionize power transmission. Or quantum tech could include the quantum computer that would exploit the entanglement of multiple electrons, resulting in a powerful way to manipulate information. And there are the quantum materials innovations we cannot yet imagine.


Studying the electrons in quantum materials

Strong interactions between electrons is an inexhaustible source of intriguing collective properties. The quantum materials we study include unconventional superconductors, spin liquids, topological insulators and Weyl semimetals, among others. Our experimental approach consists of measuring the electric, thermal and thermoelectric transport properties of these materials under different conditions of temperature, magnetic field and pressure. These measurements allow us to explore the behaviour of electrons and to describe the underlying interactions.

Quantum materials

Unconventional superconductors, spin liquids, topological insulators, Weyl semimetals.


Property of a material that allows it to transport an electric current with zero resistance and to expel a magnetic field.

Transport measurements

Electric resistivity, thermal conductivity, Hall effect, Seebeck effect, Nernst effect, Righi-Leduc effect.

Low temperatures

Two dilution fridges allow us to reach temperatures as low as a few dozen millikelvins.

Magnetic Field

Superconducting coils give us access to magnetic fields up to 20 T.

High Pressure

Our pressure cells can apply up to 2 GPa, the pressure of roughly 20 000 atmospheres.
