Relaxation of antiferromagnetic order in spin-1/2 chains following a quantum quench
Peter Barmettler, Matthias Punk, Vladimir Gritsev +2
We study the unitary time evolution of antiferromagnetic order in anisotropic Heisenberg chains that are initially prepared in a pure quantum state far from equilibrium. Our analys…

Quantum Many-Body Dynamics of Coupled Double-Well Superlattices
Peter Barmettler, Ana Maria Rey, Eugene Demler +3
We propose a method for controllable generation of non-local entangled pairs using spinor atoms loaded in an optical superlattice. Our scheme iteratively increases the distance bet…
