Abstract
We report the realization and modeling of a triple-antidot molecule hosting three interacting quantum Hall quasiparticles, with tunnel coupling between antidots tunable via the magnetic field. The measured tunneling conductance spectrum reveals the molecular energy levels arising from the interantidot coupling and Coulomb interaction. A tunneling model is established, which shows good qualitative agreement with experimental observations. In this work, we lay the foundation for the realization of complex systems of antidots for quantum Hall quasiparticles with nontrivial quantum statistics.
