  • Molecular binding in interacting quantum walks 
    Ahlbrecht, Andre; Alberti, Andrea; Meschede, Dieter; Scholz, Volkher B.; Werner, Albert H.; Werner, Reinhard F. (Bristol : IOP Publishing Ltd., 2012)
    We show that the presence of an interaction in the quantum walk of two atoms leads to the formation of a stable compound, a molecular state. The wave function of the molecule decays exponentially in the relative position ...
  • Order-Topological lattices 
    Erné, Marcel (Cambridge : Cambridge University Press, 1980)
    The observation that convergence of real sequences may be defined in terms of limits inferior and limits superior as by means of neighbourhoods in the Euclidean topology leads to the question: for which lattices does order ...
  • Perturbative 2-body parent Hamiltonians for projected entangled pair states 
    Brell, Courtney G.; Bartlett, Stephen D.; Doherty, Andrew C. (Bristol : IOP Publishing Ltd., 2014-12-22)
    We construct parent Hamiltonians involving only local 2-body interactions for a broad class of projected entangled pair states (PEPS). Making use of perturbation gadget techniques, we define a perturbative Hamiltonian ...
