Intermediate chiral edge states in quantum Hall Josephson junctions
ORAL
Abstract
A transfer matrix based theoritical framework is developed to study transport in local potential barriers modulated superconductor-quantum Hall-Superconductor (SQHS) Josephson junctions. The method allows one to identify the contribution of intermediate chiral edge states (ICES) induced by this local potential barriers at their electrostatic boundaries, to the change in Josephson conductivity at specific electron filling fractions in such SQHS Josephson junctions. It is shown that the method can be extended to study the lattice effect in a bounded domain in such SQHS Josephson junctions by submitting the normal region to a transverse magnetic field and periodic potential simultanoeusly.
