A. Prados 1, 2 E. Trizac 1 Physical Review Letters, American Physical Society, 2014, 112, pp.198001 While memory effects have been reported for dense enough disordered systems such as glasses, we show here by a combination of analytical and simulation techniques that they are also intrinsic to the dynamics of dilute granular gases. By means […]

Nechaev 2, 6, 7 Physical Review Letters, American Physical Society, 2014, 113, pp.095701 We consider random non-directed networks subject to dynamics conserving vertex degrees and study analytically and numerically equilibrium three-vertex motif distributions

Sara Jabbari-Farouji 1, 2 Jean-Jacques Weis 3 Patrick Davidson 4 Pierre Levitz 5 Emmanuel Trizac 2 Journal of Chemical Physics, American Institute of Physics (AIP), 2014, 141, pp.224510 Motivated by the intriguing phase behavior of charged colloidal platelets, we investigate the structure and dynamics of charged repulsive disks by means of Monte-Carlo simulations. The electrostatic

Joel Bun 1, 2, 3 Jean-Philippe Bouchaud 1 Satya N. Majumdar 2 Marc Potters 1 Physical Review Letters, American Physical Society, 2014, 113, pp.070201 We reconsider the large $N$ asymptotics of Harish-Chandra-Itzykson-Zuber integrals. We provide, using Dyson’s Brownian motion and the method of instantons, an alternative, transparent derivation of the Matytsin formalism for the unitary

Serguei Brazovskii 1 International school-conference on electronic crystals: ECRYS-2014, Aug 2014, Cargèse, France. 460, pp.236, Physica B: Condensed Matter We suggest a theory for a deformable and sliding charge density wave (CDW) in the Hall bar geometry for the quantum limit when the carriers in remnant small pockets are concentrated at lowest Landau levels (LL)

Andrey Y. Lokhov 1 Marc Mézard 1, 2 Hiroki Ohta 1 Lenka Zdeborová 3 Physical Review E, American Physical Society, 2014, 90, pp.012801 We study the problem of estimating the origin of an epidemic outbreak — given a contact network and a snapshot of epidemic spread at a certain time, determine the infection source. Finding

Ricardo Marino 1 Satya N. Majumdar 1 Grégory Schehr 1 Pierpaolo Vivo 1 Journal of Physics A: Mathematical and Theoretical, Institute of Physics: Hybrid Open Access, 2014, 47, pp.055001 Using a Coulomb gas technique, we compute analytically the probability $\mathcal{P}_\beta^{(C)}(N_+,N)$ that a large $N\times N$ Cauchy random matrix has $N_+$ positive eigenvalues, where $N_+$ is

Roberta Incardone 1, 2 Thorsten Emig 3 Matthias Krüger 1, 2 Europhysics Letters, EDP Science, 2014, 106, pp.41001 We theoretically study heat transfer between two anisotropic nanoparticles in vacuum, and derive closed expressions in terms of the anisotropic dipole polarizabilities. We show that transfer between two small spheroids can be many times as large as

Lenz Martin 1 Physical Review X, 2014, 4, pp.041002 Movement within eukaryotic cells largely originates from localized forces exerted by myosin motors on scaffolds of actin filaments. Although individual motors locally exert both contractile and extensile forces, large actomyosin structures at the cellular scale are overwhelmingly contractile, suggesting that the scaffold serves to favor contraction

H. H. Wensink 1 E. Trizac 2 Journal of Chemical Physics, American Institute of Physics (AIP), 2014, 140, pp.024901 The implications of soft ‘patchy’ interactions on the orientational disorder-order transition of strongly elongated colloidal rods and flat disks is studied within a simple Onsager-van der Waals density functional theory. The theory provides a generic framework
