Lenka Zdeborová 1, 2, Marc Mézard 1 Journal of Statistical Mechanics: Theory and Experiment (2008) 12004 We study the phase diagram and the algorithmic hardness of the random `locked’ constraint satisfaction problems, and compare them to the commonly studied ‘non-locked’ problems like satisfiability of boolean formulas or graph coloring. The special property of the locked problems is that clusters of

Martin R. Evans 1, Satya N. Majumdar 2 Journal of Statistical Mechanics (2008) 05004 We study the factorised steady state of a general class of mass transport models in which mass, a conserved quantity, is transferred stochastically between sites. Condensation in such models is exhibited when above a critical mass density the marginal distribution for the mass at a

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

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

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

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
