Quantum Hall Antidot as a Fractional Coulombmeter
The episode discusses a paper on using a gate-defined bilayer graphene antidot as a fractional Coulombmeter to measure quasiparticle charge in fractional quantum Hall states. Hosts discuss how this direct measurement provides concrete data, validates condensed matter theory, and offers a tool for testing anyon statistics, while also suggesting future work on controlling individual anyons.
