Effective Magnetic Monopoles and Universal Conductance Fluctuations
Kjetil M. D. Hals, Anh Kiet Nguyen, Xavier Waintal +1
The observation of isolated positive and negative charges, but not isolated magnetic north and south poles, is an old puzzle. Instead, evidence of effective magnetic monopoles has…
Intrinsic Coupling between Current and Domain Wall Motion in (Ga,Mn)As
Kjetil M. D Hals, Anh Kiet Nguyen, Arne Brataas
We consider current-induced domain wall motion and, the reciprocal process, moving domain wall-induced current. The associated Onsager coefficients are expressed in terms of scatte…
Collapse of the Quantum Wavefunction
Håkon Brox, Kåre Olaussen, Anh Kiet Nguyen
We show using a realistic Hamiltonian-type model that definite outcomes of quantum measurements may emerge from quantum evolution of pure states, i.e quantum dynamics provides a de…
External Control of a Metal-Insulator Transition in GaMnAs Wires
Anh Kiet Nguyen, Arne Brataas
Quantum transport in disordered ferromagnetic (III,Mn)V semiconductors is studied theoretically. Mesoscopic wires exhibit an Anderson disorder-induced metal-insulator transition th…
Giant current-driven domain wall mobility in (Ga,Mn)As
Anh Kiet Nguyen, Hans Joakim Skadsem, Arne Brataas
We study theoretically hole current-driven domain wall dynamics in (Ga,Mn)As. We show that the spin-orbit coupling causes significant hole reflection at the domain wall, even in th…
Intrinsic Domain Wall Resistance in Ferromagnetic Semiconductors
Anh Kiet Nguyen, R. V. Shchelushkin, Arne Brataas
Transport through zincblende magnetic semiconductors with magnetic domain walls is studied theoretically. We show that these magnetic domain walls have an intrinsic resistance due…
