Thomas Jorg 1, Florent Krzakala 2 Physical Review Letters 100 (2008) 159701 In a recent interesting Letter Contucci {\it et al.} have investigated several properties of the three-dimensional (3d) Edwards-Anderson (EA) Ising spin glass. They claim to have found strong numerical evidence for the presence of a complex ultrametric structure similar to the one described by the replica symmetry […]

P. Visco 1, 2, F. van Wijland 1, 3, E. Trizac 2 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 77 (2008) 041117 We investigate the probability distribution function of the free flight time and of the number of collisions in a hard sphere gas at equilibrium. At variance with naive expectation, the latter quantity does not follow Poissonian statistics, even in

B. Marcelis 1, 2, S. J. J. M. F. Kokkelmans 1, G. V. Shlyapnikov 2, 3, D. S. Petrov 2, 4 Physical Review A: Atomic, Molecular and Optical Physics 77 (2008) 032707 We consider collisional properties of weakly bound heteronuclear molecules (dimers) formed in a two-species mixture of atoms with a large mass difference. We focus on dimers containing light fermionic atoms as they manifest collisional

L. Chiofalo 6, 7 Physical Review A: Atomic, Molecular and Optical Physics 77 (2008) 015601 We calculate the excitation modes of a 1D dipolar quantum gas confined in a harmonic trap with frequency $\omega_0$ and predict how the frequency of the breathing n=2 mode characterizes the interaction strength evolving from the Tonks-Girardeau

R. Dubertrand 1, E. Bogomolny 1, Nadia Djellali 2, Mélanie Lebental 1, 2, C. Schmit 1 Physical Review A: Atomic, Molecular and Optical Physics 77 (2008) 013804 The construction of perturbation series for slightly deformed dielectric circular cavity is discussed in details. The obtained formulae are checked on the example of cut disks. A good agreement is found with direct numerical simulations and far-field experiments. 1.

Sahand Jamal Rahi 1, Thorsten Emig 2, 3, Robert L. Jaffe 4, Mehran Kardar 1 Physical Review A: Atomic, Molecular and Optical Physics 78 (2008) 012104 We study collective interaction effects that result from the change of free quantum electrodynamic field fluctuations by one- and two-dimensional perfect metal structures. The Casimir interactions in geometries containing plates and cylinders is explicitly computed using partial wave

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
