Entanglement growth in many-body localized systems with long-range interactions
M Pino - Physical Review B, 2014 - APS
We show that von Neumann entropy grows algebraically in time for many-body localized
systems with long-range interactions. The dephasing time of far-apart localized degrees of …

Probing matter-field and atom-number correlations in optical lattices by global nondestructive addressing
We show that light scattering from an ultracold gas reveals not only density correlations, but
also matter-field interference at its shortest possible distance in an optical lattice, which …
