Guillaume Gervais Physicist

The broad theme of Gervais’ laboratory is the search and/or study of
quantum matter on-a-chip. Material-wise, they use extremely low-disorder GaAs/AlGaAs grown in some of the best Molecular Beam Epitaxy (MBE) facilities in the World, as well as the cleanest material in Nature, liquid 3He near T=0. They carry out measurements down to ~8 mK, in high magnetic fields up to 70T.  Starting from raw semiconducting material, they tailor-fabricate structures for electrons, or nanoholes for quantum fluids using cutting-edge clean room fabrication processes evolved from the nanotech community. In Gervais’ laboratory, the search for new quantum phases of matter occurs when the nanotech tools and low-temperature know-how connect with quantum physics.

Guillaume  Gervais’  research centers on the strongly correlated
electronic properties  of  low-dimensional  nanostructured  systems very near absolute zero.  These  include  the  physics  of  two-dimensional  electrons such as fractional  quantum Hall effect, anyons and non-abelian quantum statistics; Luttinger  liquid  behaviour  in  one-dimensional  systems; ‘post-graphene’ two-dimensional  atomic  crystals ; and  experiments  testing analogies between fluid mechanics and the physics of black holes.
