"The
Many-Faceted Features of the Zero-Dimensional World:
Coulomb
interactions, Coherence, and Entanglement"
Abstract
Zero-dimensional
conductors, a.k.a. quantum dots, resemble artificial atoms in many
ways.
Such "atoms",
though, are controllable. Measurements of transport through quantum dots
involves both charge and spin degrees of freedom, and forces us to better
understand the concepts of coherence, external environment and entanglement.
I shall discuss some of the dilemmas posed by recent experiments and some
ideas for new experiments.
