How long does it take to pull an ideal polymer into a small hole?

A. Y. Grosberg 1, 2, S. Nechaev 1, 3, M. Tamm 1, 4, O. Vasilyev 3, 5 Physical Review Letters 96 (2006) 228105 We present scaling estimates for characteristic times $\tau_{\rm lin}$ and $\tau_{\rm br}$ of pulling ideal linear and randomly branched polymers of $N$ monomers into a small hole by a force $f$. We show that the absorbtion process develops as sequential straightening of folds of […]

From simple to complex networks: inherent structures, barriers and valleys in the context of spin glasses

Z. Burda, A. Krzywicki 1, O. C. Martin 2, Z. Tabor Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 73 (2006) 036110 Given discrete degrees of freedom (spins) on a graph interacting via an energy function, what can be said about the energy local minima and associated inherent structures? Using the lid algorithm in the context of a spin glass

First Experimental Observation of Superscars in a Pseudointegrable Barrier Billiard

E. Bogomolny 1, B. Dietz 2, T. Friedrich 2, M. Miski-Oglu 2, A. Richter 2, F. Schaefer 2, C. Schmit 1 Physical Review Letters 97 (2006) 254102 With a perturbation body technique intensity distributions of the electric field strength in a flat microwave billiard with a barrier inside up to mode numbers as large as about 700 were measured. A method for the reconstruction of the amplitudes and phases

Finite size scaling in Villain’s fully frustrated model and singular effects of plaquette disorder

J. Lukic 1, E. Marinari 2, O. C. Martin 3 Europhysics Letters (EPL) 73 (2006) 779-785 The ground state and low T behavior of two-dimensional spin systems with discrete binary couplings are subtle but can be analyzed using exact computations of finite volume partition functions. We first apply this approach to Villain’s fully frustrated model, unveiling an unexpected finite size scaling

Ferroelectricity and Charge Ordering in Quasi One-Dimensional Organic Conductors

Serguei Brazovskii 1, 2 x, France (2006) The family of molecular conductors TMTTF/TMTSF-X demonstrates almost all known electronic phases in parallel with a set of weak structural modifications of anion ordering and mysterious structureless transitions. Only in early 2000’s their nature became elucidated by discoveries of a huge anomaly in the dielectric permittivity and by the NMR evidences

Factorised Steady States in Mass Transport Models on an Arbitrary Graph

M. R. Evans 1, 2, Satya N. Majumdar 3, R. K. P. Zia 4 Journal of Physics A 39 (2006) 4859-4873 We study a general mass transport model on an arbitrary graph consisting of $L$ nodes each carrying a continuous mass. The graph also has a set of directed links between pairs of nodes through which a stochastic portion of mass, chosen
