Alberto Rosso 1, Pierre Le Doussal 2, Kay Joerg Wiese 2 Physical Review B 75 (2007) 22020a We compute numerically the sequence of successive pinned configurations of an elastic line pulled quasi-statically by a spring in a random bond (RB) and random field (RF) potential. Measuring the fluctuations of the center of mass of the line allows to obtain the functional […]

Thierry Jolicoeur 1 Physical Review Letters 99 (2007) 036805 By applying the idea of parafermionic clustering to composite bosons with positive as well as negative flux, a new series of trial wavefunctions to describe fractional quantum Hall states is proposed. These non-Abelian states compete at filling factors k/(3k +/- 2) with other ground states like stripes or

Z. Burda 1, A. Krzywicki 2, O. C. Martin 3 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 76 (2007) 051107 The local minima (inherent structures) of a system and their associated transition links give rise to a network. Here we consider the topological and distance properties of such a network in the context of spin glasses. We use steepest

Silvio Franz 1, Giorgio Parisi 2, 3, 4, Federico Ricci-Tersenghi 2 Journal of Physics A: Mathematical and General 41 (2007) 324011 In this paper we study finite interaction range corrections to the mosaic picture of the glass transition as emerges from the study of the Kac limit of large interaction range for disordered models. To this aim we consider point to set correlation

Martina Hentschel 1, Georg Roeder 1, Denis Ullmo 2 Progress of Theoretical Physics Supplement 166 (2007) 143-151 Many-body phenomena, a key interest in the investigation of bulk solid state systems, are studied here in the context of the x-ray edge problem for mesoscopic systems. We investigate the many-body effects associated with the sudden perturbation following the x-ray excitation of a core

F. Liers 1, O. C. Martin 2 Physical Review B 76 (2007) 060405 The magnetic critical properties of two-dimensional Ising spin glasses are controversial. Using exact ground state determination, we extract the properties of clusters flipped when increasing continuously a uniform field. We show that these clusters have many holes but otherwise have statistical properties similar to those of

Paul Zinn-Justin 1 Journal of Statistical Mechanics: Theory and Experiment (2007) P01007 The integrable loop model with mixed boundary conditions based on the 1-boundary extended Temperley–Lieb algebra with loop weight 1 is considered. The corresponding qKZ equation is introduced and its minimal degree solution described. As a result, the sum of the properly normalized components of the
