Entanglement versus Correlations in Spin Systems
F. Verstraete, M. Popp, J. I. Cirac
We consider pure quantum states of spins or qubits and study the average entanglement that can be \emph{localized} between two separated spins by performing local measurem…

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…
