Edmond Orignac 1, Alberto Rosso 2, R. Chitra 3, T. Giamarchi 4 Physical Review B 73 (2006) 035112 We study the effect of unscreened charged impurities on periodic systems. We show that the long wavelength component of the disorder becomes long ranged and dominates static correlation functions. On the other hand, because of the statistical tilt symmetry, dynamical properties such as pinning remain

J. Umrigar 2, Denis Ullmo 1, 3, Harold U. Baranger 1 Nature Physics 2 (2006) 336-340 Physical properties of the « electron gas » — in which conduction electrons interact via Coulomb forces but the ionic potential is neglected — change dramatically depending on the balance between the strength of the kinetic energy and the Coulomb repulsion. The limiting cases

A. Braunstein 1, M. Mezard 2, M. Weigt 3, R. Zecchina 1 Computational Complexity and Statistical Physics 107 (2006) part 2 : 4 Survey Propagation is an algorithm designed for solving typical instances of random constraint satisfiability problems. It has been successfully tested on random 3-SAT and random $G(n,\frac{c}{n})$ graph 3-coloring, in the hard region of the parameter space. Here we provide a

K. Jain 2 Journal of Physics B 39 (2006) S89-S99 Ultracold neutral bosons in a rapidly rotating atomic trap have been predicted to exhibit fractional quantum Hall-like states. We describe how the composite fermion theory, used in the description of the fractional quantum Hall effect for electrons, can be applied to interacting

The interaction favors parallel alignment of dimers, resulting in a low-temperature crystalline phase. With large-scale Monte
