โœฆ Synopsis

The energy level structure of an interacting system of electrons is analysed. The model chosen describes electrons in a semiconductor quantum dot system, whose energy levels could be accessed via finite-bias transport experiments. We find that the normalized level spacing of the system exhibits significant departures from Poisson statistics, and that these are strongly dependent on magnetic field, and quantum numbers of the level sequence.

We study the model of two interacting particles moving in a 1D box, paying main attention to the quantum-classical correspondence for the average shape of quantum eigenstates and for the local density of states (LDOS). We show that if the classical motion is chaotic, in a deep semi-classical region
