D. S. Petrov 1 F. Werner 2 Physical Review A, American Physical Society, 2015, 92, pp.022704 Within the universal zero-range theory, we compute the three-body recombination rate to deep molecular states for two identical bosons resonantly interacting with each other and with a third atom of another species, in the absence of weakly bound dimers.

Fabrizio Altarelli 1, 2 Alfredo Braunstein 3, 1, 2 Luca Dall’Asta 1, 2 Caterina De Bacco 4 Silvio Franz 4 PLoS ONE, Public Library of Science, 2015, 10, pp.0145222 We present a message-passing algorithm to solve the edge disjoint path problem (EDP) on graphs incorporating under a unique framework both traffic optimization and path length

Andrea De Luca 1 Pierre Le Doussal 2 Physical Review E : Statistical, Nonlinear, and Soft Matter Physics, American Physical Society, 2015, 92, pp.040102 We study the probability that two directed polymers in the same random potential do not intersect. We use the replica method to map the problem onto the attractive Lieb-Liniger model with

Clélia De Mulatier 1, 2 Eric Dumonteil 3 Alberto Rosso 2 Andrea Zoia 1 Journal of Statistical Mechanics: Theory and Experiment, IOP Science, 2015, pp.P08021 The neutron population in a prototype model of nuclear reactor can be described in terms of a collection of particles confined in a box and undergoing three key random mechanisms:

Juan Pablo Mallarino 1 Gabriel Tellez 1 Emmanuel Trizac 2 Molecular Physics, Taylor & Francis, 2015, 113, pp.2409 When a Coulombic fluid is confined between two parallel charged plates, an exact relation links the difference of ionic densities at contact with the plates, to the surface charges of these boundaries. It no longer applies when

Caterina De Bacco 1 Satya N. Majumdar 1 Peter Sollich 2 Journal of Physics A: Mathematical and Theoretical, Institute of Physics: Hybrid Open Access, 2015, 48, pp.205004 We study the linear large $n$ behavior of the average number of distinct sites $S(n)$ visited by a random walker after $n$ steps on a large random graph.

O. Giraud 1 D. Braun 2 D. Baguette 3 T. Bastin 3 J. Martin 3 Physical Review Letters, American Physical Society, 2015, 114, pp.080401 We propose a generalization of the Bloch sphere representation for arbitrary spin states. It provides a compact and elegant representation of spin density matrices in terms of tensors that share the

Marie Chupeau 1 Olivier Bénichou 1 Satya N. Majumdar 2 Physical Review E : Statistical, Nonlinear, and Soft Matter Physics, American Physical Society, 2015, 91, pp.032106 We study the survival probability and the first-passage time distribution for a Brownian motion in a planar wedge with infinite absorbing edges. We generalize existing results obtained for wedge

Fengcheng Wu 1 Inti Sodemann 1 Allan H. Macdonald 1 Thierry Jolicoeur 2 Physical Review Letters, American Physical Society, 2015, 115, pp.166805 We report on an exact diagonalization study of fractional quantum Hall states at filling factor $\nu=2/3$ in a system with a four-fold degenerate $n$=0 Landau level and SU(4) symmetric Coulomb interactions. Our investigation

Stefan Mashkevich 1, 2 Stéphane Ouvry 3 Alexios Polychronakos 4 Journal of Physics A: Mathematical and Theoretical, IOP Publishing, 2015, 48, pp.405001 We focus on the algebraic area probability distribution of planar random walks on a square lattice with $m_1$, $m_2$, $l_1$ and $l_2$ steps right, left, up and down. We aim, in particular, at
