Extended slow dynamical regime close to the many-body localization transition
David J. Luitz, Nicolas Laflorencie, Fabien Alet
Many-body localization is characterized by a slow logarithmic growth of the entanglement entropy after a global quantum quench while the local memory of an initial density imbalanc…
Entanglement entropies of the Heisenberg antiferromagnet on the square lattice
Nicolas Laflorencie, David J. Luitz, Fabien Alet
Using a modified spin-wave theory which artificially restores zero sublattice magnetization on finite lattices, we investigate the entanglement properties of the Néel ordered $J_1…
Universal logarithmic corrections to entanglement entropies in two dimensions with spontaneously broken continuous symmetries
David J. Luitz, Xavier Plat, Fabien Alet +1
We explore the Rényi entanglement entropies of a one-dimensional (line) subsystem of length embedded in two-dimensional square lattice for quantum spin models whose…
Manipulating the magnetic state of a carbon nanotube Josephson junction using the superconducting phase
R. Delagrange, D. J. Luitz, R. Weil +4
The magnetic state of a quantum dot attached to superconducting leads is experimentally shown to be controlled by the superconducting phase difference across the dot. This is done…
