Dynamics and Asymptotics of Correlations in a Many-Body Localized System
Steve Campbell, Matthew J. M. Power, Gabriele De Chiara
We examine the dynamics of nearest-neighbor bipartite concurrence and total correlations in the spin-1/2 model with random fields. We show, starting from factorized random in…
Non-Gaussian distribution of collective operators in quantum spin chains
M. Moreno-Cardoner, J. F. Sherson, G. De Chiara
We numerically analyse the behavior of the full distribution of collective observables in quantum spin chains. While most of previous studies of quantum critical phenomena are limi…
Dynamical symmetry breaking with optimal control: reducing the number of pieces
Matthew J. M. Power, Gabriele De Chiara
We analyse the production of defects during the dynamical crossing of a mean-field phase transition with a real order parameter. When the parameter that brings the system across th…
Full characterization of the quantum linear-zigzag transition in atomic chains
Pietro Silvi, Gabriele De Chiara, Tommaso Calarco +2
A string of repulsively interacting particles exhibits a phase transition to a zigzag structure, by reducing the transverse trap potential or the interparticle distance. The transi…
