Matias Rodrigues 4, Jürgen Jost 1, 5, Olivier C. Martin 2, 6, Andreas Wagner 4, 5, 7, 8 BMC Biology 4 (2010) 30 Background: A metabolic genotype comprises all chemical reactions an organism can catalyze via enzymes encoded in its genome. A genotype is viable in a given environment if it is capable of producing all biomass components the organism needs to survive and reproduce. […]

Yan V Fyodorov 1, Pierre Le Doussal 2, Alberto Rosso 3 Europhysics Letters (EPL) 90 (2010) 60004 We reveal a phase transition with decreasing viscosity $\nu$ at \nu=\nu_c>0 in one-dimensional decaying Burgers turbulence with a power-law correlated random profile of Gaussian-distributed initial velocities 1.

Pasquale Calabrese 1, Pierre Le Doussal 2, Alberto Rosso 3 Europhysics Letters (EPL) 90 (2010) 20002 We study the directed polymer of length $t$ in a random potential with fixed endpoints in dimension 1+1 in the continuum and on the square lattice, by analytical and numerical methods. The universal regime of high temperature $T$ is described, upon scaling ‘time’ $t \sim

M. V. Milovanović 1, Th. Jolicoeur 2 International Journal of Modern Physics B 24 (2010) 549 We investigate the structure of gapless edge modes propagating at the boundary of some fractional quantum Hall states. We show how to deduce explicit trial wavefunctions from the knowledge of the effective theory governing the edge modes. In general quantum Hall states have

I. L. Aleiner 1, B. L. Altshuler 2, G. V. Shlyapnikov 3, 4 Nature Physics 6 (2010) 900-904 It is commonly accepted that there are no phase transitions in one-dimensional (1D) systems at a finite temperature, because long-range correlations are destroyed by thermal fluctuations. Here we demonstrate that the 1D gas of short-range interacting bosons in the presence of disorder can undergo

Guillaume Roux 1 Physical Review A: Atomic, Molecular and Optical Physics 81 (2010) 053604 We investigate finite size effects in quantum quenches on the basis of simple energetic arguments. Distinguishing between the low-energy part of the excitation spectrum, below a microscopic energy-scale, and the high-energy regime enables one to define a crossover number of particles that is

M. Colomé-Tatché 1, S. I. Matveenko 1, 2, G. V. Shlyapnikov 1, 3 Physical Review A: Atomic, Molecular and Optical Physics 81 (2010) 013611 We study finite size effects for the gap of the quasiparticle excitation spectrum in the weakly interacting regime one-dimensional Hubbard model with on-site attraction. Two type of corrections to the result of the thermodynamic limit are obtained. Aside from

S. Bittner 1, E. Bogomolny 2, B. Dietz 3, M. Miski-Oglu 3, P. Oria Iriarte 1, A. Richter 1, 4, F. SchÄfer 5 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 81 (2010) 066215 Resonance spectra of two-dimensional dielectric microwave resonators of circular and square shapes have been measured. The deduced length spectra of periodic orbits were analyzed and a trace formula for dielectric resonators recently proposed by Bogomolny

Hajime Yoshino 1, Marc Mezard 2 Physical Review Letters 105 (2010) 015504 We compute the shear modulus of structural glasses from a first principle approach based on the cloned liquid theory. We find that the intra-state shear-modulus, which corresponds to the plateau modulus measured in linear visco-elastic measurements, strongly depends on temperature and vanishes continuously when the temperature is
