D. M. Gangardt 1, S. K. Nechaev 2, 3 Journal of Statistical Physics 130 (2008) 483-502 We consider wetting of a one-dimensional random walk on a half-line $x\ge 0$ in a short-ranged potential located at the origin $x=0$. We demonstrate explicitly how the presence of a quenched chemical disorder affects the pinning-depinning transition point. For small disorders we develop a

M. V. Tamm 1, S. K. Nechaev 2 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 78 (2008) 011903 We have analyzed the dependence of average ground state energy per monomer, $e$, of the complex of two random heteropolymers with quenched sequences, on chain length, $n$, in the ensemble of chains with uniform distribution of primary sequences. Every

Thomas Jorg 1, Helmut G. Katzgraber 2 Physical Review B 77 (2008) 214426 We study the four-dimensional Ising spin glass with Gaussian and bond-diluted bimodal distributed interactions via large-scale Monte Carlo simulations and show via an extensive finite-size scaling analysis that four-dimensional Ising spin glasses obey universality. 1.

Satya N. Majumdar 1, Robert M. Ziff 2 Physical Review Letters 101 (2008) 050601 It is shown that statistics of records for time series generated by random walks are independent of the details of the jump distribution, as long as the latter is continuous and symmetric. In N steps, the mean of the record distribution grows as the sqrt(4N/pi)

M. Colomé-Tatché 1 Physical Review A: Atomic, Molecular and Optical Physics 78 (2008) 033612 We study the two-component repulsive Fermi gas with imbalanced populations in one dimension. Starting from the Bethe Ansatz solution we calculate analytically the phase diagram for the homogeneous system. We show that two phases appear: the fully polarised phase and the partially polarised

E. Bogomolny 1, R. Dubertrand 1, C. Schmit 1 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 78 (2008) 056202 The construction of the trace formula for open dielectric cavities is examined in detail. Using the Krein formula it is shown that the sum over cavity resonances can be written as a sum over classical periodic orbits for the motion

S. Bustingorry 1, A. B. Kolton 2, A. Rosso 3, W. Krauth 4, T. Giamarchi 5 Physica B: Condensed Matter 404 (2008) 444-446 Many seemingly different macroscopic systems (magnets, ferroelectrics, CDW, vortices,..) can be described as generic disordered elastic systems. Understanding their static and dynamics thus poses challenging problems both from the point of view of fundamental physics and of practical applications. Despite important progress
