  1. Existence of negative differential thermal conductance in one-dimensional diffusive thermal transport.

    Physical Review E 87(6):062104 (2013) PMID 23848624

    We show that in a finite one-dimensional (1D) system with diffusive thermal transport described by the Fourier's law, negative differential thermal conductance (NDTC) cannot occur when the temperature at one end is fixed and there are no abrupt junctions. We demonstrate that NDTC in this case requir...
  2. MRI evidence for a receding-front effect in drying porous media.

    Physical Review E 87(6):062303 (2013) PMID 23848671

    We propose a protocol to observe simultaneously the distributions of air, liquid, and colloid through the unsaturated solid porous structure. Thus we show that the above phenomenon comes from a receding-front effect: The elements migrate towards the free surface of the sample and accumulate in the r...
  3. Static fluctuations of a thick one-dimensional interface in the 1+1 directed polymer formulation: numerical study.

    Physical Review E 87(6):062405 (2013) PMID 23848695

    We study numerically the geometrical and free-energy fluctuations of a static one-dimensional (1D) interface with a short-range elasticity, submitted to a quenched random-bond Gaussian disorder of finite correlation length ξ>0 and at finite temperature T. Using the exact mapping from the static 1D i...
  4. Nematic fluctuations and semisoft elasticity in liquid-crystal elastomers.

    Physical Review E 87(6):062509 (2013) PMID 23848707

    We give a detailed theory of nematic fluctuations in liquid-crystal elastomers (LCEs) and calculate relaxation rates as obtained by dynamic light scattering (DLS). In ideal LCEs, a nematic state is formed by a spontaneous orientational symmetry breaking of an isotropic state, manifesting itself in a...
  5. Nonequilibrium chemistry in confined environments: a lattice Brusselator model.

    Physical Review E 87(6):062923 (2013) PMID 23848764

    We study the effect of molecular crowding on a typical example of a chemical oscillator: the Brusselator model. We adopt to this end a nonequilibrium thermodynamic description, in which the size of particles is introduced via a lattice gas model. The impenetrability and finite volume of the species...
  6. Synchronous equilibrium model for the diffusion of mutually exclusive particles in a heterogeneous lattice of adsorption sites.

    Physical Review E 87(6):063306 (2013) PMID 23848805

    We constructed a synchronous, non-glass-forming rule for diffusion of mutually exclusive particles in a lattice of adsorption sites. The rule satisfies detailed balance in the presence of both homogeneous and heterogeneous adsorption energies. Our model differs from the usual lattice-gas cellular au...
  7. Aging processes in systems with anomalous slow dynamics.

    Physical Review E 87(1-1):012114 (2013) PMID 23410290

    We here study two simple driven systems-the one-dimensional ABC model and a related domain model with simplified dynamics-that are known to exhibit anomalous slow relaxation where the asymptotic logarithmic growth regime is readily accessible. Studying two-times correlation and response functions, w...
  8. Equilibration and thermalization of the dissipative quantum harmonic oscillator in a nonthermal environment.

    Physical Review E 87(1-1):012127 (2013) PMID 23410303

    We study the dissipative quantum harmonic oscillator with general nonthermal preparations of the harmonic oscillator bath. The focus is on equilibration of the oscillator in the long-time limit and the additional requirements for thermalization. Our study is based on the exact solution of the micros...
  9. Atomic force microscopy study of surface topography of films of cholesteric oligomer- and polymer-based mixtures with photovariable helix pi...

    Physical Review E 87(1-1):012503 (2013) PMID 23410345

    The surface topography of glass-forming polymers and oligomer cholesteric systems with a phototunable helix pitch was studied. For this purpose several mixtures based on nematic polyacrylate and cholesteric cyclosiloxanes doped with chiral-photochromic dopant were prepared and invest...
  10. Improved contact prediction in proteins: Using pseudolikelihoods to infer Potts models.

    Physical Review E 87(1-1):012707 (2013) PMID 23410359

    We show that the pseudolikelihood method, applied to 21-state Potts models describing the statistical properties of families of evolutionarily related proteins, significantly outperforms existing approaches to the direct-coupling analysis, the latter being based on standard mean-field techniques.
