Entanglement Resonance in Driven Spin Chains
Fernando Galve, David Zueco, Sigmund Kohler +2
We consider a spin-1/2 anisotropic XY model with time-dependent spin-spin coupling as means of creating long-distance entanglement. We predict the emergence of significant entangle…

Nonexponential decoherence and momentum subdiffusion in a quantum Lévy kicked rotator
Henning Schomerus, Eric Lutz
We investigate decoherence in the quantum kicked rotator (modelling cold atoms in a pulsed optical field) subjected to noise with power-law tail waiting-time distributions of varia…
