Effect of inter-edge interaction in a quantum Hall collider

Amulya Ratnakar, Flavio Ronetti, Benoît Grémaud +4

Fractional quantum Hall (FQH) colliders measure anyon exchange phases via time-domain braiding, but the state exhibits an intriguing negative Fano factor, challenging theo…

Hanbury Brown-Twiss interferometry at the fractional quantum Hall edge

Ryotaro Sano, Fumihiro Murabayashi, Daigo Ichikawa +5

We propose a Hanbury Brown-Twiss interferometer for a fractional quantum Hall edge system, in which quasiparticles tunnel between two co-propagating edge modes. In contras…

Microwave response of fractional quantum Hall droplets with quasiparticle tunneling

Fumihiro Murabayashi, Ryotaro Sano, Flavio Ronetti +5

We theoretically study microwave absorption spectroscopy of fractional quantum Hall droplets in the presence of quasiparticle tunneling across a quantum point contact. This contact…

Anyon braiding on the single edge of a fractional quantum Hall state

Flavio Ronetti, Noé Demazure, Jérôme Rech +6

Anyons are quasiparticles with fractional statistics, bridging between fermions and bosons. We propose an experimental setup to measure the statistical angle of topological anyons…

Probing anyon statistics on a single-edge loop in the fractional quantum Hall regime

Flavio Ronetti, Noé Demazure, Jérôme Rech +6

We propose a setup to directly measure the anyonic statistical angle on a single edge of a fractional quantum Hall system, without requiring independent knowledge of non-universal…

Photo-assisted shot noise probes multiple charge carriers in quantum Hall edges

Kishore Iyer, Flavio Ronetti, Benoît Grémaud +3

Fractional charges in the fractional quantum Hall effect were first observed via DC shot noise measurements of anyons tunneling at a quantum point contact (QPC). However, in scenar…
