Abstract

Recent work on the role of decoherence in quantum physics has suggested that the quantum to classical decay is governed by a discrete set of pointer states, which are quite stable and uncoupled from other states in the system. We show that the conductance oscillations exhibited by open quantum dots are governed by a discrete set of stable quantum states which have the properties of the pointer states, and which are closely related to trapped classical orbits in the open dot. These states are essentially classical in nature, as evidenced by their energy level spacing, and their decay is apparently in the environment as opposed to within the dots.
