  • Entanglement negativity and sudden death in the toric code at finite temperature 

    Hart, Oliver; Castelnovo, Claudio (APS, 2018-04-16)
    We study the fate of quantum correlations at finite temperature in the two dimensional toric code using the logarithmic entanglement negativity. We are able to obtain exact results that give us insight into how thermal ...
  • Dynamic scaling of topological ordering in classical systems 

    Xu, N; Castelnovo, Claudio; Melko, RG; Chamon, C; Sandvik, AW (American Physical Society, 2018-01-29)
    We analyze scaling behaviors of simulated annealing carried out on various classical systems with topological order, obtained as appropriate limits of the toric code in two and three dimensions. We first consider the ...
  • Semiclassical dynamics, Berry curvature, and spiral holonomy in optical quasicrystals 

    Spurrier, Stephen; Cooper, Nigel Robert (APS, 2018-04-03)
    We describe the theory of the dynamics of atoms in two-dimensional quasicrystalline optical lattices. We focus on a regime of shallow lattice depths under which the applied force can cause Landau-Zener tunnelling past ...
  • Materials data validation and imputation with an artificial neural network 

    Verpoort, Philipp; MacDonald, P; Conduit, Gareth John (Elsevier, 2018-05-01)
    We apply an artificial neural network to model and verify material properties. The neural network algorithm has a unique capability to handle incomplete data sets in both training and predicting, so it can regard properties ...
