This prize is awarded “for groundbreaking experiments that uncovered the role of vortices in the superfluid phase transition in helium films and observed anyonic braiding statistics of quasiparticles in the fractional quantum Hall effect, thus establishing the significance of topological excitations in two-dimensions”.
The work of the Mesoscopic Physics team at LPENS, in collaboration with C2N, has revealed the fractional statistics of anyons in two-particle interferometry experiments, also known as Hong-Ou-Mandel interferometry.
The Oliver E. Buckley de Condensed Matter Physics Prize of APS recognizes and encourages outstanding theoretical or experimental contributions to condensed matter physics. The prize consists of $20,000. It is awarded annually.
