Query: Microwave Absorption by a Mesoscopic Quantum Hall Droplet   We consider the absorption of microwaves by a quantum Hall droplet. We show
that the number and velocities of charged edge modes can be directly measured
from a droplet of known shape. In contrast to standard transport measurements,
different edge equilibration regimes can be accessed in the same device. If
there is a quantum point contact in the droplet, then quasiparticle properties,
including braiding statistics, can be observed. Their effects are manifested as
modulations of the microwave absorption spectrum that are, notably, first-order
in the tunneling amplitude at the point contact.
