T. Emig 1, 2, N. Graham 3, 4, R. L. Jaffe 4, M. Kardar 5 Physical Review D 77 (2008) 025005 We have developed an exact, general method to compute Casimir interactions between a finite number of compact objects of arbitrary shape and separation. Here, we present details of the method for a scalar field to illustrate our approach in its most simple form; the […]

T. Emig 1, 2, R. L. Jaffe 3 Journal of Physics A General Physics 41 (2008) 164001 We develop an exact method for computing the Casimir energy between arbitrary compact objects, both with boundary conditions for a scalar field and dielectrics or perfect conductors for the electromagnetic field. The energy is obtained as an interaction between multipoles, generated by quantum

M. I. Garcia de Soria 1, P. Maynar 2, 3, E. Trizac 1 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 78 (2008) 061110 The behavior of a heavy tagged intruder immersed in a bath of particles evolving under ballistic annihilation dynamics is investigated. The Fokker-Planck equation for this system is derived and the peculiarities of the corresponding diffusive behavior are

J. J. Brey 1, M. I. Garcia de Soria 2, P. Maynar 1, 3 Europhysics Letters (EPL) 84 (2008) 24002 A numerical molecular dynamics experiment measuring the two-time correlation function of the transversal velocity field in the homogeneous cooling state of a granular gas is reported. By measuring the decay rate and the amplitude of the correlations, the accuracy of the Landau-Langevin

Satya N. Majumdar 1, Kirone Mallick 2, Sergei K. Nechaev 1 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 77 (2008) 011110 For the Bernoulli Matching model of sequence alignment problem we apply the Bethe ansatz technique via an exact mapping to the 5-vertex model on a square lattice. Considering the terrace-like representation of the sequence alignment problem, we reproduce by

Thomas Jorg 1, Helmut G. Katzgraber 2, Florent Krzakala 3 Physical Review Letters 100 (2008) 197202 We study the existence of a spin-glass phase in a field using Monte Carlo simulations performed along a nontrivial path in the field–temperature plane that must cross any putative de Almeida-Thouless instability line. The method is first tested on the Ising spin glass on a

Z. Burda 1, A. Krzywicki 2, O. C. Martin 3 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 78 (2008) 046106 Multi-agent models have been used in many contexts to study generic collective behavior. Similarly, complex networks have become very popular because of the diversity of growth rules giving rise to scale-free behavior. Here we study adaptive networks where the
