Universality versus material dependence of fluctuation forces between metallic wires

Ehsan Noruzifar 1, Thorsten Emig 2, Roya Zandi 1 Physical Review A 84 (2011) 042501 We calculate the Casimir interaction between two parallel wires and between a wire and a metall plate. The dielectric properties of the objects are described by the plasma, Drude and perfect metal models. We find that at asymptotically large separation interactions involving plasma wires and/or plates

Trace formula for dielectric cavities II: Regular, pseudo-integrable, and chaotic examples

E. Bogomolny 1, N. Djellali 2, R. Dubertrand 3, I. Gozhyk 2, M. Lebental 2, C. Schmit 1, C. Ulysse 4, J. Zyss 2 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 83 (2011) 036208 Dielectric resonators are open systems particularly interesting due to their wide range of applications in optics and photonics. In a recent paper [PRE, vol. 78, 056202 (2008)] the trace formula for both the smooth and

Topological p_x+ip_y Superfluid Phase of Fermionic Polar Molecules

J. Levinsen 1, 2, N. R. Cooper 1, 2, G. V. Shlyapnikov 1, 3 Physical Review A 84 (2011) 013603 We discuss the topological p_x+ip_y superfluid phase in a 2D gas of single-component fermionic polar molecules dressed by a circularly polarized microwave field. This phase emerges because the molecules may interact with each other via a potential V_0(r) that has an attractive dipole-dipole 1/r^3

Tkachenko modes and their damping in the vortex lattice regime of rapidly rotating bosons

S. I. Matveenko 1, 2, G. V. Shlyapnikov 1, 3 Physical Review A: Atomic, Molecular and Optical Physics 83 (2011) 033604 We have found an exact analytical solution of the Bogoliubov-de Gennes equations for the Tkachenko modes of the vortex lattice in the lowest Landau level (LLL) in the thermodynamic limit at any momenta and calculated their damping rates. At finite

Thermal noise and dephasing due to electron interactions in non-trivial geometries

M. Treiber 1, C. Texier 2, 3, O. M. Yevtushenko 1, J. von Delft 1, I. V. Lerner 4 Physical Review B 84 (2011) 054204 We study Johnson-Nyquist noise in macroscopically inhomogeneous disordered metals and give a microscopic derivation of the correlation function of the scalar electric potentials in real space. Starting from the interacting Hamiltonian for electrons in a metal and the random phase approximation,

The convex hull for a random acceleration process in two dimensions

Alexis Reymbaut, Satya N. Majumdar 1, Alberto Rosso 1 Journal of Physics A: Mathematical and Theoretical 44, 41 (2011) 415001 We compute exactly the mean perimeter and the mean area of the convex hull of a random acceleration process of duration T in two dimensions. We use an exact mapping that relates, via Cauchy’s formulae, the computation of the perimeter

Supersymmetric quantum mechanics with Levy disorder in one dimension

Alain Comtet 1, 2, Christophe Texier 2, 3, Yves Tourigny 4 Journal of Statistical Physics 145 (2011) 1291-1323 We consider the Schroedinger equation with a supersymmetric random potential, where the superpotential is a Levy noise. We focus on the problem of computing the so-called complex Lyapunov exponent, whose real and imaginary parts are, respectively, the Lyapunov exponent and the integrated density of states
