Nicolas Bilas 1, Nicolas Pavloff 1 European Physical Journal D 40 (2006) 387-397 We study the elementary excitations of a transversely confined Bose-Einstein condensate in presence of a weak axial random potential. We determine the localization length (i) in the hydrodynamical low energy regime, for a domain of linear densities ranging from the Tonks-Girardeau to the transverse Thomas-Fermi regime, […]

Serguei Brazovskii 1, 2 Synthetic Metals 152 (2005) 309-312 Victor Emery made seminal contributions to the theory of one-dimensional electronic systems and to its applications to organic metals. His inventions became illuminated recently when the joint effect of the ferroelectricity and the charge disproportionation has been discovered in (TMTTF)2X compounds and beyond. Several of his contributions came to

S. Sinha 1, G. V. Shlyapnikov 2, 3 Physical Review Letters 94 (2005) 150401 We show that a Bose-condensed gas under extreme rotation in a 2D anisotropic trap, forms a novel elongated quantum fluid which has a roton-maxon excitation spectrum. For a sufficiently large interaction strength, the roton energy reaches zero and the system undergoes a second order quantum transition

Stefano Ciliberti 1, Marc Mezard 1 Journal of Statistical Mechanics: Theory and Experiment 1 (2005) P10003 The Parity Source Coder is a protocol for data compression which is based on a set of parity checks organized in a sparse random network. We consider here the case of memoryless unbiased binary sources. We show that the theoretical capacity saturate the

David S. Dean 1, 2, David Lancaster 3, Satya Majumdar 4 Journal of Statistical Mechanics: Theory and Experiment 1 (2005) L01001 We study the finite temperature statistical mechanics of Hamiltonian paths between a set of N quenched randomly distributed points in a finite domain D. The energy of the path is a function of the distance between neighboring points on the path, an

Satya N. Majumdar 1, M. R. Evans 2, R. K. P. Zia 3 Physical Review Letters 94 (2005) 180601 We study the phenomenon of real space condensation in the steady state of a class of one dimensional mass transport models. We derive the criterion for the occurrence of a condensation transition and analyse the precise nature of the shape and the
