    1. Viscous quark-gluon plasma in the early universe (pages 194–207)

      A. Tawfik, M. Wahba, H. Mansour and T. Harko

      Version of Record online: 2 NOV 2010 | DOI: 10.1002/andp.201000052

      In the present work a study is given for the evolution of a flat, isotropic and homogeneous universe, which is filled with a causal bulk viscous cosmological fluid. The authors describe the viscous properties by an ultra-relativistic equation of state, and bulk viscosity coefficient obtained from recent lattice QCD calculations. The basic equation for the Hubble parameter is derived by using the energy equation obtained from the assumption of the covariant conservation of the energy-momentum tensor of the matter in the universe. …

    2. An extension of Khalatnikov's theory of Kapitsa thermal resistance (pages 208–225)

      B.V. Budaev and D.B. Bogy

      Version of Record online: 15 DEC 2010 | DOI: 10.1002/andp.201000111

      This paper develops a novel approach to Kapitsa thermal resistance which extends Khalatnikov's acoustic mismatch theory by inclusion of a previously excluded broad class of acoustic waves that violate the Sommerfeld radiation condition, which is essential for the theory of sound but is not relevant for the analysis of heat transport. …

    3. Necessity of acceleration-induced nonlocality (pages 226–234)

      B. Mashhoon

      Version of Record online: 10 JAN 2011 | DOI: 10.1002/andp.201010464

      The purpose of this paper is to explain clearly why nonlocality must be an essential part of the theory of relativity. In the standard local version of this theory, Lorentz invariance is extended to accelerated observers by assuming that they are pointwise inertial. …

    4. Did Günter Nimtz discover tachyons? (pages 235–238)

      E. Kapuścik and R. Orlicki

      Version of Record online: 20 DEC 2010 | DOI: 10.1002/andp.201000118

      It is argued that in the famous G. Nimtz experiment tachyons were produced and annihilated. The authors base their considerations on the new version of Special Relativity elaborated recently by one of the authors.

    5. The relativistic Doppler effect: when a zero-frequency shift or a red shift exists for sources approaching the observer (pages 239–246)

      C. Wang

      Version of Record online: 20 DEC 2010 | DOI: 10.1002/andp.201000099

      It is shown without making use of Lorentz transformation that there exists a phenomenon of relativistic zero-frequency shift in Doppler effect for a plane wave in free space, observed in two inertial frames of relative motion, and the zero shift takes place at a maximum aberration of light. When it is applied to analysis of a moving point light source, two unconventional physical implications result: (1) a light source, when it is approaching (moving closer to) the observer, may cause a red shift; (2) a zero-frequency-shift observation does not necessarily mean that the light source is not moving closer, and in contrast, the light source may be moving closer to the observer at a high speed. …

    6. Methodology for the solutions of some reduced Fokker-Planck equations in high dimensions (pages 247–258)

      G.K. Er

      Version of Record online: 10 JAN 2011 | DOI: 10.1002/andp.201010465

      In this paper, a new methodology is formulated for solving the reduced Fokker-Planck (FP) equations in high dimensions based on the idea that the state space of large-scale nonlinear stochastic dynamic system is split into two subspaces. The FP equation relevant to the nonlinear stochastic dynamic system is then integrated over one of the subspaces. The FP equation for the joint probability density function of the state variables in another subspace is formulated with some techniques. Therefore, the FP equation in high-dimensional state space is reduced to some FP equations in low-dimensional state spaces, which are solvable with exponential polynomial closure method. Numerical results are presented and compared with the results from Monte Carlo simulation and those from equivalent linearization to show the effectiveness of the presented solution procedure. …

    7. Charge transfer effects on the Fermi surface of Ba0.5K0.5Fe2As2 (pages 259–264)

      S. Nazir, Z.Y. Zhu and U. Schwingenschlögl

      Version of Record online: 31 JAN 2011 | DOI: 10.1002/andp.201000113

      Ab-initio calculations within density functional theory are performed to obtain a more systematic understanding of the electronic structure of iron pnictides. As a prototypical compound the authors study Ba0.5K0.5Fe2As2 and analyze the changes of its electronic structure when the interaction between the Fe2As2 layers and their surrounding is modified. They find strong effects on the density of states near the Fermi energy as well as the Fermi surface. The role of the electron donor atoms …
