Nuclear spin dynamics in semiconductor nanostructures

Abstract

I will discuss recent advances in understanding the nuclear spin dynamics in low dimensional systems. The focus will be on the hyperfine interaction between nuclear and electronic spins and the role this interaction plays on the dynamical nuclear polarization of semiconductor nanostructures. I will address topics such as nuclear spin relaxation time, nuclear spin polarization, and nuclear spin diffusion. As an example I will consider the case of semiconductor quantum wells and discuss theoretical results in connection with experimental data.
