Nad 4 International school-conference on electronic crystals: ECRYS-2014, Aug 2014, Cargèse, France. 460, pp.79, Physica B: Condensed Matter The quasi one-dimensional organic conductor (TMTTF)2AsF6 shows the charge ordering transition at Tc101K to a state of the ferroelectric Mott insulator which is still well conducting. We present […]

L. Samaj 1, 2 E. Trizac 1 Journal of Statistical Physics, Springer Verlag (Germany), 2014, 156, pp.932 This work contributes to the problem of determining effective interaction between asymmetrically (likely or oppositely) charged objects whose total charge is neutralized by mobile pointlike counter-ions of the same charge, the whole system being in thermal equilibrium. The

Juraj Szavits-Nossan 1 Martin R. Evans 1 Satya N. Majumdar 2 Physical Review Letters, American Physical Society, 2014, 112, pp.020602 Condensation is the phenomenon whereby one of a sum of random variables contributes a finite fraction to the sum. It is manifested as an aggregation phenomenon in diverse physical systems such as coalescence in granular

Juraj Szavits-Nossan 1 Martin R. Evans 1 Satya N. Majumdar 2 Journal of Physics A: Mathematical and Theoretical, Institute of Physics: Hybrid Open Access, 2014, 47, pp.455004 Real space condensation is known to occur in stochastic models of mass transport in the regime in which the globally conserved mass density is greater than a critical

Zoia AndreaDumonteil EricMazzolo AlainDe Mulatier CléliaRosso Alberto Physical Review E, American Physical Society, 2014, 90, pp.042118 We study the evolution of a collection of individuals subject to Brownian diffusion, reproduction and disappearance. In particular, we focus on the case where the individuals are initially prepared at equilibrium within a confined geometry. Such systems are widespread

A recent work [S. Gupta and D. Mukamel, J. Stat. Mech.: Theory Exp. P03015 (2011)]

Mazzolo Alain 1 De Mulatier Clélia 2, 3 Zoia Andrea 4 Journal of Mathematical Physics, American Institute of Physics (AIP), 2014, 55, pp.083308 Cauchy’s formula was originally established for random straight paths crossing a body $B \subset \mathbb{R}^{n}$ and basically relates the average chord length through $B$ to the ratio between the volume and the

Giuseppe Bimonte 1 Thorsten Emig 2 Mehran Kardar 3 Physical Review D, American Physical Society, 2014, 90, pp.081702 We use a derivative expansion for gently curved surfaces to compute the leading and the next-to-leading curvature corrections to the Casimir-Polder interaction between a polarizable small particle and a non-planar surface. While our methods apply to any

Y. Y. Atas 1 E. Bogomolny 1 Philosophical transactions of the Royal Society of London. Series A: Mathematical and physical sciences, Royal Society, The, 2014, 372, pp.20120520 It was demonstrated in [Phys. Rev. E 86, 021104, (2012)], that the ground-state wave functions for a large variety of one-dimensional spin-1/2 models are multifractals in the natural

Jan Mölter 1 Thomas Barthel 2, 1 Ulrich Schollwöck 1 Vincenzo Alba 1 Journal of Statistical Mechanics, 2014, pp.P10029 We investigate entanglement properties of the excited states of the spin-1/2 Heisenberg (XXX) chain with isotropic antiferromagnetic interactions, by exploiting the Bethe ansatz solution of the model. We consider eigenstates obtained from both real and complex
