We describe how, exploiting the current scanning near-field optical techniques, it is possible to map phase and modulus of the wavefunctions of a quantum dot system. In particular we propose an experimental setup based on an interferometric technique able to measure simultaneously modulus and phase of wavefunctions. We present numerical calculations simulating the measurements on dots arising from interface fluctuations of GaAs quantum wells.

Abstract
We describe how, exploiting the current scanning near-field optical techniques, it is possible to map phase and modulus of the wavefunctions of a quantum dot system. In particular we propose an experimental setup based on an interferometric technique able to measure simultaneously modulus and phase of wavefunctions. We present numerical calculations simulating the measurements on dots arising from interface fluctuations of GaAs quantum wells.File in questo prodotto:
