Abstract

Through a detailed comparison of experiment and theory, we show that the features observed in the low temperature magnetoresistance of open quantum dots may be interpreted as arising from a magnetospectroscopy of their discrete density of states. At temperatures where ensemble averaging is only weakly effective, we find that the position and width of various peaks observed in this magnetoresistance may be associated with a resonance structure that is closely related to the density of states. This association can even be made in situations where the dot is strongly coupled to an external environment.
