Anyon fractional statistics in mesoscopic colliders
Our team investigates the fractional statistics of anyons using the geometry of anyon colliders, where two dilute beams of anyons are generated at the input of an anyon beam splitter. We have focused so far on abelian anyons, for which the accumulated phase associated to the exchange of two particles can take arbitrary values between 0 (bosonic case) and π (fermionic case). We use high mobility GaAs/AlGaAs heterostructures under a strong magnetic field to reach the fractional quantum Hall effect whose elementary excitations are anyons. By sending anyon excitations towards a beam-splitter and by measuring the correlations between the output electrical currents, we can probe the tendency of anyons to bunch together at the splitter output, which provides information on their fractional statistics.

Quantum skyrmionics
Our team theoretically studies the quantum and nonequilibrium skyrmion dynamics with a focus on developing strategies for bringing a novel macroscopic qubit design based on magnetic skyrmions to fruition. In particular, we aim to understand the microscopic mechanisms that create noise, design schemes to control sources of decoherence built upon spectral engineering, study the coherent interaction of skyrmion qubits with other quantum modules, and achieve long-distance tunable qubit coupling.
