Electrons in Quantum Wires

Abstract: Electronic properties of one-dimensional conductors are modified drastically by the interaction between electrons. Many of the modifications are adequately represented by the Luttinger liquid picture, while understanding of some phenomena requires going beyond it. The unusual properties of one-dimensional electron transport include the suppression of tunneling conductance, electron spin-charge separation, and an enhanced Coulomb drag effect. The talk reviews theory and some experiments in this growing research field, and describes its relation to the physics of other low-dimensional systems.
