I am currently working on unconventional superconductors and quantum spin liquids at a fundamental level, with tools such thermal experiments in extreme conditions at low temperature and high magnetic field

OUTREACH

Physicists from University of Sherbrooke led an international team to first direct measurement of the critical magnetic field in cuprates, the most promising materials for superconductivity

ARTICLE

For the first time, the upper critical field H_c2 of a cuprate is directly measured using thermal conductivity in high magnetic field. Our result shows there is no vortex liquid in the zero temperature limit and reveals the importance of phase competition in the cuprates.
