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…
Nonclassicality and criticality in symmetry-protected magnetic phases
Matthew J. M. Power, Steve Campbell, Maria Moreno-Cardoner +1
Quantum and global discord in a spin-1 Heisenberg chain subject to single-ion anisotropy (uniaxial field) are studied using exact diagonalisation and the density matrix renormalisa…
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…
