    1. Resonance-like Goos-Hänchen shift induced by nano-metal films (pages 917–921)

      The influence of nano-metal films on the Goos-Hänchen shift (GHS) is investigated. The films were deposited at the total reflecting surface of a perspex prism and had a sheet resistance varying between Z = 25 and 3 000 Ω. A resonance-like enhancement of the shift and of the absorption is found for TE polarized waves, when the sheet resistance approached the value of the vacuum impedance. For TM waves the influence of the metal films on the GHS was marginal. The experiments were carried out with microwaves.

    2. DMRG studies of critical SU(N) spin chains (pages 922–936)

      The DMRG method is applied to integrable models of antiferromagnetic spin chains for fundamental and higher representations of SU(2), SU(3), and SU(4). From the low energy spectrum and the entanglement entropy, we compute the central charge and the primary field scaling dimensions. These parameters allow us to identify uniquely the Wess–Zumino–Witten models capturing the low energy sectors of the models we consider.

    3. Matter waves in terms of the unitary representations of the Lorentz group (pages 937–946)

      R.A. Frick

      Version of Record online: 20 NOV 2008 | DOI: 10.1002/andp.200710327

      In a generalized Heisenberg/Schrödinger picture, the unitary representations of the Lorentz group may, for a massive relativistic particle, be used to attribute to waves an extra wavelength that is longer than the de Broglie wavelength. Propagators are defined as spacetime transitions between states with different eigenvalues of the first or the second Casimir operator of the Lorentz algebra.

    4. Superfluid to Mott-insulator transition in an anisotropic two-dimensional optical lattice (pages 947–954)

      T.P. Polak and T.K. Kopeć

      Version of Record online: 20 NOV 2008 | DOI: 10.1002/andp.200810328

      e study the superfluid to Mott-insulator transition of bosons in an optical anisotropic lattice by employing the Bose-Hubbard model living on a two-dimensional lattice with anisotropy parameter κ. The compressible superfluid state and incompressible Mott-insulator (MI) lobes are efficiently described analytically, using the quantum U(1) rotor approach. The ground state phase diagram ...

    5. Approximate record length constraints for experimental identification of dynamical fractals (pages 955–969)

      S.W. Fleming

      Version of Record online: 20 NOV 2008 | DOI: 10.1002/andp.200810329

      The ambiguity that can exist, for short datasets, between the observational power spectra of dynamical fractals and low-order linear memory processes is demonstrated and explained. It is argued that it could be broadly useful to have a highly practical rule-of-thumb for assessing whether a data record is sufficiently long to permit distinguishing the two types of processes, and ...
