Chiara D Errico 1, 2 Eleonora Lucioni 1, 2 Luca Tanzi 1 Lorenzo Gori 1 Guillaume Roux 3 Ian P. McCulloch 4 Thierry Giamarchi 5 Massimo Inguscio 1, 6 Giovanni Modugno 1, 2 Physical Review Letters, American Physical Society, 2014, 113, pp.095301 We employ ultracold atoms with controllable disorder and interaction to study the paradigmatic […]

A. M. Kamchatnov 1 Y. V. Kartashov 1 P. -É. Larré 2 N. Pavloff 2 Physical Review A, American Physical Society, 2014, 89, pp.033618 Waves with different symmetries exist in two-component Bose-Einstein condensates (BECs) whose dynamics is described by a system of coupled Gross-Pitaevskii (GP) equations. A first type of waves corresponds to excitations for

Shamik Gupta 1 Alessandro Campa 2 Stefano Ruffo 3 Physical Review E, American Physical Society, 2014, 89, pp.022123 We study the dynamics of a system of coupled oscillators of distributed natural frequencies, by including the features of both thermal noise, parametrized by a temperature, and inertial terms, parametrized by a moment of inertia. For a

Tridib Sadhu 1 Satya N. Majumdar 2 David Mukamel 3 Journal of Physics A: Mathematical and Theoretical, Institute of Physics: Hybrid Open Access, 2014, 47, pp.505005 In equilibrium, the effect of a spatially localised perturbation is typically confined around the perturbed region. Quite contrary to this, in a non-equilibrium stationary state often the entire system

Caterina De Bacco 1 Fulvio Baldovin 2 Enzo Orlandini 2 Ken Sekimoto 3, 4 Physical Review Letters, American Physical Society, 2014, 112, pp.180605 We propose a new look at the heat bath for two Brownian particles, in which the heat bath as a ‘system’ is both perturbed and sensed by the Brownian particles. Non-local thermal

Anthony Perret 1 Gregory Schehr 1 Journal of Statistical Physics, Springer Verlag (Germany), 2014, 156, pp.843-876 We study the phenomenon of « crowding » near the largest eigenvalue $\lambda_{\max}$ of random $N \times N$ matrices belonging to the Gaussian Unitary Ensemble (GUE) of random matrix theory. We focus on two distinct quantities: (i) the density of states

Pierre Ronceray 1, 2 Peter Harrowell 3 Physical Review Letters, American Physical Society, 2014, 112, pp.017801 We present here a numerical study of a lattice model of a chiral liquid. The low symmetry of the favoured local structure depresses the freezing point to reveal an exotic liquid-liquid transition characterised by the appearance of an extended

Vivek Kandiah 1 Bertrand Georgeot 1 Olivier Giraud 2 The European Physical Journal B, Springer, 2014, 87, pp.246. <10.1140/epjb/e2014-50497-1> We analyze the game of go from the point of view of complex networks. We construct three different directed networks of increasing complexity, defining nodes as local patterns on plaquettes of increasing sizes, and links as

Alvaro Rojo Bravo 1 Tianyou Yi 2 Natasha Kirova 3, 4 Serguei Brazovskii 1, 3 International school-conference on electronic crystals: ECRYS-2014, Aug 2014, Cargèse, France. 460, pp.16, Physica B: Condensed Matter We derive and study equations for dissipative transient processes in a constraint incommensurate charge density wave (CDW) with remnant pockets or a thermal population

E. A. Jagla 1 François P. Landes 2 Alberto Rosso 2 Physical Review Letters, American Physical Society, 2014, 112, pp.174301 Many complex systems respond to continuous input of energy by accumulation of stress over time and sudden energy releases in the form of avalanches. Avalanches are paradigmatic non-equilibrium phenomena displaying power law size distribution and
