  2. 1. Effects of aperiodic order for Josephson junction arrays and discrete breathers

    Author : Erik Lennholm; Linköpings universitet; []
    Keywords : Aperiodic order; Josephson junction array; Discrete breather;

    Abstract : Effects of the combination of nonlinearities and aperiodic order is studied in this thesis. The nonlinear systems considered are Josephson junction arrays (JJA) and Fermi-Pasta-Ulam (FPU) lattices. Both systems are discrete and one-dimensional. The traveling waves in a JJA are solitons, i.

  4. 2. Physical effects of nonlinearity in discrete onedimensional systems with spatial variations

    Author : Erik Lennholm; Luis Mario Floria; Linköpings universitet; []
    Keywords : ;

    Abstract : Physical properties of a solid are affected, to a very high degree, by the spatial structure of the material at hand. This thesis is concerned with such effects in nonlinear systems. In itself, nonlinearity is a subject on the move, and more and more areas of physics tend to take nonlinear effects into account. READ MORE
