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…
Local quench spectroscopy of many-body quantum systems
L. Villa, J. Despres, S. J. Thomson +1
Quench spectroscopy is a relatively new method which enables the investigation of spectral properties of many-body quantum systems by monitoring the out-of-equilibrium dynamics of…
Unraveling the Excitation Spectrum of Many-Body Systems from Quantum Quenches
Louis Villa, Julien Despres, Laurent Sanchez-Palencia
Quenches are now routinely used in synthetic quantum systems to study a variety of fundamental effects, including ergodicity breaking, light-cone-like spreading of information, and…
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…
Universal Scaling Laws for Correlation Spreading in Quantum Systems with Short- and Long-Range Interactions
Lorenzo Cevolani, Julien Despres, Giuseppe Carleo +2
We study the spreading of information in a wide class of quantum systems, with variable-range interactions. We show that, after a quench, it generally features a double structure,…
Majorana fermions in finite-size strips with in-plane magnetic fields
Vardan Kaladzhyan, Julien Despres, Ipsita Mandal +1
We study the Majorana bound states arising in quasi-one-dimensional systems with Rashba spin-orbit coupling in the presence of an in-plane Zeeman magnetic field. Using two differen…
