Query: Wave function description of conductance mapping for quantum Hall
  electron interferometer   Scanning gate microscopy of quantum point contacts (QPC) in the integer
quantum Hall regime is considered in terms of the scattering wave functions
with a finite-difference implementation of the quantum transmitting boundary
approach. Conductance ($G$) maps for a clean QPC as well as for a system
including an antidot within the constriction are evaluated. The step-like
locally flat $G$ maps for clean QPCs turn into circular resonances that are
reentrant in external magnetic field when the antidot is introduced to the
constriction.
  The current circulation around the antidot and the spacing of the resonances
at the magnetic field scale react to the probe approaching the QPC. The
calculated $G$ maps with a rigid but soft antidot potential reproduce the
features detected recently in the electron interferometer [F. Martins et al.
Nature Sci. Rep. 3, 1416 (2013)].
