Entanglement in the quantum Ising model
Geoffrey Grimmett, Tobias Osborne, Petra Scudo
We study the asymptotic scaling of the entanglement of a block of spins for the ground state of the one-dimensional quantum Ising model with transverse field. When the field is suf…
Bounds on Information Propagation in Disordered Quantum Spin Chains
Christian K. Burrell, Tobias J. Osborne
We investigate the propagation of information through the disordered XY model. We find, with a probability that increases with the size of the system, that all correlations, both c…
Exact relaxation in a class of non-equilibrium quantum lattice systems
M. Cramer, C. M. Dawson, J. Eisert +1
A reasonable physical intuition in the study of interacting quantum systems says that, independent of the initial state, the system will tend to equilibrate. In this work we study…
