Inhomogenous model of crossing loops and multidegrees of some algebraic varieties

P. Di Francesco 1, Paul Zinn-Justin 2 Communications in Mathematical Physics 262 (2006) 459-487 We consider a quantum integrable inhomogeneous model based on the Brauer algebra B(1) and discuss the properties of its ground state eigenvector. In particular we derive various sum rules, and show how some of its entries are related to multidegrees of algebraic varieties. 1. Service […]

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
