Paul Zinn-Justin 1 Nuclear Physics B 634 (2002) 417 The expression of the large $N$ Harish Chandra–Itzykson–Zuber (HCIZ) integral in terms of the moments of the two matrices is investigated using an auxiliary unitary two-matrix model, the associated biorthogonal polynomials and integrable hierarchy. We find that the large $N$ HCIZ integral is governed by the dispersionless Toda

Marc Mézard 1 More is different, Ong and Bhatt editors 1 (2002) 1 This paper is an introduction to some of the main present issues in the theory of structural glasses. After recalling a few experimental facts, it gives a short account of the analogy between fragile glasses and the mean field discontinuous spin glasses. The many

Alain Comtet 1, 2, Satya N. Majumdar 3 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 66 (2002) 061105 We obtain exact asymptotic results for the disorder averaged persistence of a Brownian particle moving in a biased Sinai landscape. We employ a new method that maps the problem of computing the persistence to the problem of finding the energy spectrum

Jaroslaw Piasecki, Emmanuel Trizac 1, 2, Michel Droz Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 66 (2002) 066111 The problem of ballistically controlled annihilation is revisited for general initial velocity distributions and arbitrary dimension. An analytical derivation of the hierarchy equations obeyed by the reduced distributions is given, and a scaling analysis of the corresponding spatially homogeneous system

M. Sasaki 1, O. C. Martin 1, 2 Physical Review B 66 (2002) 174411 Within generalized random energy models, we study the effects of energy discreteness and of entropy extensivity in the low temperature phase. At zero temperature, discreteness of the energy induces replica symmetry breaking, in contrast to the continuous case where the ground state is unique. However, when

M. Sasaki 1, V. Dupuis 2, J. -P. Bouchaud 2, E. Vincent 2 European Physical Journal B 29 (2002) 469 We study the deviations from perfect memory in negative temperature cycle spin glass experiments. It is known that the a.c. susceptibility after the temperature is raised back to its initial value is superimposed to the reference isothermal curve for large enough temperature jumps

Florent Krzakala 1, Olivier C. Martin 1 European Physical Journal B 20 (2002) 199 We address the problem of chaotic temperature dependence in disordered glassy systems at equilibrium by following states of a random-energy random-entropy model in temperature; of particular interest are the crossings of the free-energies of these states. We find that this model exhibits strong, weak or no

Nicolas Pavloff 1 Physical Review A: Atomic, Molecular and Optical Physics 66 (2002) 013610 The 1D flow of a continuous beam of Bose-Einstein condensed atoms in the presence of an obstacle is studied as a function of the beam velocity and of the type of perturbing potential (representing the interaction of the obstacle with the atoms of
