Jean-Sebastien Bernier 1, 2, Dario Poletti 3, Peter Barmettler 3, Guillaume Roux 4, Corinna Kollath 1, 5 Physical Review A 85 (2012) 033641 We investigate the dynamics of Mott-insulating regions of a trapped bosonic gas as the interaction strength is changed linearly with time. The bosonic gas considered is loaded into an optical lattice and confined to a parabolic trapping potential. Two situations are addressed: the formation […]

Thomas Gueudre 1, Pierre Le Doussal 1, Alberto Rosso 2, Adrien Henry 2, Pasquale Calabrese 3 Physical Review E 86 (2012) 041151 The short time behavior of the 1+1 dimensional KPZ growth equation with a flat initial condition is obtained from the exact expressions of the moments of the partition function of a directed polymer with one endpoint free and the other fixed. From these

Vladimir A. Baulin 1, 2, Emmanuel Trizac 3 Soft Matter 8 (2012) 2755-2766 The formation of inter-polyelectrolyte complexes from the association of oppositely charged polymers in an electrolyte is studied. The charged polymers are linear oppositely charged polyelectrolytes, with possibly a neutral block. This leads to complexes with a charged core, and a more dilute corona of dangling chains, or

Gregor Wergen 1, Satya N. Majumdar 2, Gregory Schehr 2 Physical Review E 86 (2012) 011119 We study the statistics of the number of records R_{n,N} for N identical and independent symmetric discrete-time random walks of n steps in one dimension, all starting at the origin at step 0. At each time step, each walker jumps by a random length drawn

Satya N. Majumdar 1, Gregory Schehr 1, Gregor Wergen 2 Journal of Physics A General Physics 45 (2012) 355002 We study the statistics of records of a one-dimensional random walk of n steps, starting from the origin, and in presence of a constant bias c. At each time-step the walker makes a random jump of length \eta drawn from a continuous

Iacopo Mastromatteo 1, Elia Zarinelli 2, Matteo Marsili 3 Journal of Statistical Mechanics: Theory and Experiment (2012) P03011 In this paper we estimate the propagation of liquidity shocks through interbank markets when the information about the underlying credit network is incomplete. We show that techniques such as Maximum Entropy currently used to reconstruct credit networks severely underestimate the risk of contagion

Sara Jabbari-Farouji 1, 2, 3, Paul Van Der Schoot 2, 4 Journal of Chemical Physics 137 (2012) 064906 As a first step to understanding the role of molecular or chemical polydispersity in self-assembly, we put forward a coarse-grained model that describes the spontaneous formation of quasi-linear polymers in solutions containing two self-assembling species. Our theoretical framework is based on a two-component self-assembled

T. Wasak 1, J. Chwedenczuk 1, M. Trippenbach 1, 2, Pawel Zin 2, 3 Physical Review A 86 (2012) 043621 It is demonstrated that measurements of positions of atoms scattered from a quasi-condensate in a Raman process provide information on the temperature of the parent cloud. In particular, the widths of the density and second order correlation functions are sensitive to the phase fluctuations induced
