Query: Probing Electron-Electron Interactions with a Quantum Antidot   In the integer quantum Hall (IQH) regime, an antidot provides a finite,
controllable `edge' of quantum Hall fluid that is an ideal laboratory for
investigating the collective dynamics of large numbers of interacting
electrons. Transport measurements of single antidots probe the excitation
spectra of the antidot edge, and gate-defined antidot devices offer the
flexibility to vary both the antidot's dimensions and its couplings to extended
IQH edge modes which serve as leads. We also use the spin-selectivity of the
IQH edge modes to perform spin-resolved transport measurements, from which we
can infer the antidot spin-structure. This thesis describes a combination of
such transport experiments and related computational models designed to
investigate the effects of electron-electron interactions in quantum antidots,
with general implications for the physics of spin and charge in IQH systems.
