  1. Energy pumping in electrical circuits under avalanche noise.

    Physical Review E 90(1-1):012115 (2014) PMID 25122259

    We theoretically study energy pumping processes in an electrical circuit with avalanche diodes, where non-Gaussian athermal noise plays a crucial role. We show that a positive amount of energy (work) can be extracted by an external manipulation of the circuit in a cyclic way, even when the system is...
  2. Reinterpretation of velocity-dependent atomic friction: Influence of the inherent instrumental noise in friction force microscopes.

    Physical Review E 90(1-1):012125 (2014) PMID 25122269

    We have applied both the master equation method and harmonic transition state theory to interpret the velocity-dependent friction behavior observed in atomic friction experiments. To understand the discrepancy between attempt frequencies measured in atomic force microscopy experiments and those esti...
  3. Kinetic Monte Carlo simulations of proton conductivity.

    Physical Review E 90(1-1):012135 (2014) PMID 25122279

    We showed in detail that the relative frequency of reorientation and diffusion processes is crucial for the conductivity. Moreover, the current dependence on proton concentration has been analyzed. In order to test our microscopic model the proton transport in polymer electrolyte membranes based on...
  4. Nonequilibrium dynamics of four-point correlations of collective density fluctuations in a supercooled liquid.

    Physical Review E 90(1-1):012137 (2014) PMID 25122281

    We study the four-point correlation function χ_{4} of collective density fluctuations in a nonequilibrium liquid. The equilibration is controlled by a modified stretched exponential behavior {exp[-(t_{w}/τ)^{β}]} having the relaxation time τ dependent on the aging time t_{w}. Similar aging behavior...
  5. Effect of disorder on condensation in the lattice gas model on a random graph.

    Physical Review E 90(1-1):012144 (2014) PMID 25122288

    The lattice gas model of condensation in a heterogeneous pore system, represented by a random graph of cells, is studied using an exact analytical solution. A binary mixture of pore cells with different coordination numbers is shown to exhibit two phase transitions as a function of chemical potentia...
  6. Characteristics of angular cross correlations studied by light scattering from two-dimensional microsphere films.

    Physical Review E 90(1-1):012309 (2014) PMID 25122305

    We apply this CCA approach to ultra-small-angle light-scattering data obtained from two-dimensional monolayers of microspheres. The films were studied in addition by optical microscopy. This combined approach allows to calculate the cross-correlations of the scattering patterns, characterized by the...
  7. Electric-field variations within a nematic-liquid-crystal layer.

    Physical Review E 90(1-1):012503 (2014) PMID 25122320

    We use calculus of variations to derive the equations coupling the electric potential to the orientation of the NLC's director field, and use a simple one-dimensional model to investigate the limitations of the uniform field assumption in the case of a steady applied field. The extension of the mode...
  8. Rheology of twist-grain-boundary-A liquid crystals.

    Physical Review E 90(1-1):012506 (2014) PMID 25122323

    We report studies on the rheological properties of a liquid crystalline analog of Abrikosov phase in type-II superconductors known as twist-grain-boundary-A (TGB_{A}) phase. The TGB_{A} phase shows a large apparent yield stress compared to the cholesteric (N^{*}) phase. The storage modulus (G^{^{'}}...
  9. Suppressing epidemics on networks by exploiting observer nodes.

    Physical Review E 90(1-1):012807 (2014) PMID 25122342

    We investigate the effect of observer nodes that recognize infection in a neighboring node and make the rest of the neighbor nodes immune. We numerically show that random placement of observer nodes works better on networks with clustering than on locally treelike networks, implying that our model i...
  10. Solutions of the higher-order Manakov-type continuous and discrete equations.

    Physical Review E 90(1-1):012902 (2014) PMID 25122355

    We derive exact and approximate localized solutions for the Manakov-type continuous and discrete equations. We establish the correspondence between the solutions of the coupled Ablowitz-Ladik equations and the solutions of the coupled higher-order Manakov equations.
