Abstract :
The authors consider an approach to the magneto-transport fluctuations in ballistic quantum dots, based upon the energy spectra of the dots. The results obtained from these calculations allows us to probe issues regarding the scaling of the dominant frequency of the fluctuations. From our numerical analysis we attempt to resolve this issue by simulating dots of many different sizes using a quantum mechanical approach.
