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.

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.
