Effects of coupling strength and edge disorder on coherent transport through a quantum Hall antidot system

In an quantum Hall (QH) antidot, quasi particles of QH fluid can be localized and organized in quantized energy levels. In this work, we used hBN encapsulated graphene samples to study the coherent transport properties through QH antidot systems. In those samples the utilization of side gates and co-axial gate leads to great tunability in coupling between antidot and charge reservoir as well as individual intra antidots coupling, which allows the characterization of effects from coupling strength and edge disorders on the quantum coherence. This pave ways for achieving more complex QH antidots systems as hosts of anyons with exotic exchange statistics.
