Theory of spin waves in diluted-magnetic-semiconductor quantum wells
Diego Frustaglia, Jürgen König, Allan H. MacDonald
We present a theory of collective spin excitations in diluted-magnetic-semiconductor quantum wells in which local magnetic moments are coupled via a quasi-two-dimensional gas of el…
Spin interference effects in ring conductors subject to Rashba coupling
Diego Frustaglia, Klaus Richter
Quantum interference effects in rings provide suitable means for controlling spin at mesoscopic scales. Here we apply such control mechanisms to coherent spin-dependent transport i…
Conditions for Adiabatic Spin Transport in Disordered Systems
Markus Popp, Diego Frustaglia, Klaus Richter
We address the controversy concerning the necessary conditions for the observation of Berry phases in disordered mesoscopic conductors. For this purpose we calculate the spin-depen…
Spin Filter Effects in Mesoscopic Ring Structures
Markus Popp, Diego Frustaglia, Klaus Richter
We study the spin-dependent conductance of ballistic mesoscopic ring systems in the presence of an inhomogeneous magnetic field. We show that, for the setup proposed, even a small…
