Correlation Spreading in Quantum Lattice Models with Variable-Range Interactions
Julien Despres
In this thesis, we have investigated the spreading of quantum correlations in isolated lattice models with short- or long-range interactions driven far from equilibrium via sudden…

Spreading of Correlations and Entanglement in the Long-Range Transverse Ising Chain
J. T. Schneider, J. Despres, S. J. Thomson +2
Whether long-range interactions allow for a form of causality in non-relativistic quantum models remains an open question with far-reaching implications for the propagation of info…

Twofold correlation spreading in a strongly correlated lattice Bose gas
J. Despres, L. Villa, L. Sanchez-Palencia
We study the spreading of correlations in the Bose-Hubbard chain, using the time-dependent matrix-product state approach. In both the superfluid and the Mott-insulator phases, we f…
