Abstract

Scanning gate microscopy (SGM) is used to image scar structures in an InAs open quantum dot, which is defined via electron beam lithography and wet etching. Periodicities in magnetic field are found within the scanned images and correlate to those observed in the conductance fluctuations. Simulations have shown that these magnetic transform images show striking resemblance to actual scars found in the dot that replicate through the conductance modes in direct agreement with the theory of quantum Darwinism.
