Dear Colleagues,

Spintronics – or spin-electronics – is an emerging technology which aims to revolutionize traditional electronics by combining the well-known functionalities derived from the charge of carriers (usually electrons or “holes”) with the properties of their spin degrees of freedom. These can be exploited by engineering interactions between spins and electric or magnetic fields. Alternatively spin behaviour can be influenced by the environment offered by different materials, or by constraints due to the system geometry, or by its patterning with nano-structures.

‘Spintronics’ encompasses by now many different subfields and interlaces with spin-based quantum information. While valuable progress and discoveries have been made so far, important open questions remain, from optimizing spin injection in semiconductor device elements to improving understanding and control of spin dynamics and coherence. This special issue focuses on this mixture of prospective applications and open fundamental problems to provide exciting science and technology for many years to come.

Title: Spin and charge excitations in low dimensional electron liquids
Author: Dr. Florent Perez
Affiliation: Institut des NanoSciences de Paris, Université Pierre et Marie Curie, Paris, France
Abstract: We review 15 years of optical exploration of low energy spin and charge excitations, like plasmons, spin-plasmons, spin-waves and individual excitations, of electron gases confined in semi-conductor quantum wells and wires. The electronic Raman scattering probe has, during these years, proven its efficiency in the accurate determination of the dispersion of these excitations. These explorations aimed at improving the understanding of the Coulomb interaction between confined electrons. Recently, the introduction of test-bed spin-polarized electron gases gave an experimental access to spin-resolved Coulomb interactions. Very recently, intriguing interplay between spin-orbit and Coulomb interactions has been discovered.
