Half-metal phases in a quantum wire with modulated spin-orbit interaction
D. C. Cabra, G. L. Rossini, A. Ferraz +2
We propose a spin valve device based on the interplay of a modulated spin-orbit interaction and a uniform external magnetic field acting on a quantum wire. Half-metal phases, where…

Decoherence from spin environments: Loschmidt echo and quasiparticle excitations
R. Jafari, Henrik Johannesson
We revisit the problem of decoherence of a qubit centrally coupled to an interacting spin environment, here modeled by a quantum compass chain or an extended XY model in a staggere…
