Victor J. Emery and recent applications of his ideas

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 …

Two-dimensional Bose-Einstein Condensate under extreme rotation

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 …

The statistical mechanics of traveling salesman type problems

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 …

The cavity method for large deviations

Olivier Rivoire 1 Journal of Statistical Mechanics: Theory and Experiment 1 (2005) P04007 A method is introduced for studying large deviations in the context of statistical physics of disordered systems. The approach, based on an extension of the cavity method to atypical realizations of the quenched disorder, allows us to compute exponentially small probabilities (rate functions) over …
