E. Bogomolny 1, S. Mashkevich 2, 3, S. Ouvry 1 Journal of Physics A Mathematical and Theoretical 43 (2010) 354029 The scattering of an incident plane wave on two Aharonov-Bohm vortices with opposite fluxes is considered in detail. The presence of the vortices imposes non-trivial boundary conditions for the partial waves on a cut joining the two vortices. These conditions result in […]

Vicente Garzo 1, Emmanuel Trizac 2 Journal of Non-Newtonian Fluid Mechanics 165 (2010) 932-940 The Boltzmann equation for inelastic Maxwell models is considered to determine the rheological properties in a granular binary mixture in the simple shear flow state. The transport coefficients (shear viscosity and viscometric functions) are {\em exactly} evaluated in terms of the coefficients of restitution, the

Guillaume Roux 1 Physical Review A: Atomic, Molecular and Optical Physics 82 (2010) 037602 In his Comment [see preceding Comment, Phys. Rev. A 82, 037601 (2010)] on the paper by Roux [Phys. Rev. A 79, 021608(R) (2009)], Rigol argued that the energy distribution after a quench is not related to standard statistical ensembles and cannot explain thermalization.

Michele Castellana 1, 2, Giorgio Parisi 3 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 82, 4 (2010) 040105 The infrared behaviour of a non-mean field spin-glass system is analysed, and the critical exponent related to the divergence of the correlation length is computed at two loops within the epsilon-expansion technique with two independent methods. Both methods yield the

Satya N. Majumdar 1, Alain Comtet 1, Julien Randon-Furling 2 Journal of Statistical Physics 138, 6 (2010) 955-1009 In this paper we study the statistical properties of convex hulls of $N$ random points in a plane chosen according to a given distribution. The points may be chosen independently or they may be correlated. After a non-exhaustive survey of the somewhat sporadic

Roya Zandi 1, Thorsten Emig 2, 3, Umar Mohideen 1 Physical Review B 81 (2010) 195423 We calculate the Casimir interaction between a sphere and a plate, both described by the plasma model, the Drude model, or generalizations of the two models. We compare the results at both zero and finite temperatures. At asymptotically large separations we obtain analytical results for the

Nicolas Destainville 1, Bertrand Georgeot 1, Olivier Giraud 1, 2 Physical Review Letters 104 (2010) 250502 We build a quantum algorithm which uses the Grover quantum search procedure in order to sample the exact equilibrium distribution of a wide range of classical statistical mechanics systems. The algorithm is based on recently developed exact Monte Carlo sampling methods, and yields a polynomial gain

P. Sulc 1, A. Wagner 2, 3, O. C. Martin 1, 4 Journal of Bioinformatics and Computational Biology 8 (2010) 1027-1040 We re-examine the evolutionary dynamics of RNA secondary structures under directional selection towards an optimum RNA structure. We find that the punctuated equilibria lead to a very slow approach to the optimum, following on average an inverse power of the evolutionary time.

Olivier Giraud 1, 2, Petr A. Braun 3, 4, Daniel Braun 1 New Journal of Physics 12 (2010) 063005 We introduce a measure of  »quantumness » for any quantum state in a finite dimensional Hilbert space, based on the distance between the state and the convex set of classical states. The latter are defined as states that can be written as a convex sum

Alain Comtet 1, 2, Christophe Texier 2, 3, Yves Tourigny 4 Journal of Statistical Physics 140 (2010) 427-466 To every product of $2\times2$ matrices, there corresponds a one-dimensional Schr\'{o}dinger equation whose potential consists of generalised point scatterers. Products of {\em random} matrices are obtained by making these interactions and their positions random. We exhibit a simple one-dimensional quantum model corresponding to the most
