Alternative statistical-mechanical descriptions of decaying two-dimensional turbulence in terms of "patches" and "points"

Z. Yin, D. C. Montgomery, H. J. H. Clercx

Numerical and analytical studies of decaying, two-dimensional (2D) Navier-Stokes (NS) turbulence at high Reynolds numbers are reported. The effort is to determine computable distin…

Infinitely-fast diffusion in Single-File Systems

s. V. Nedea, A. P. J. Jansen, J. J. Lukkien

We have used Dynamic Monte Carlo (DMC) methods and analytical techniques to analyze Single-File Systems for which diffusion is infinitely-fast. We have simplified the Master Equati…

Commutator-errors in large-eddy simulation

Bernard J. Geurts, Darryl D. Holm

A new formulation is derived for the commutator-errors in large-eddy simulation of incompressible flow. These commutator-errors arise from the application of non-uniform filters to…

Feshbach resonances in rubidium 87: Precision measurement and analysis

A. Marte, T. Volz, J. Schuster +4

More than 40 Feshbach resonances in rubidium 87 are observed in the magnetic field range between 0.5 and 1260 G for various spin mixtures in the lower hyperfine ground state. The F…

Kinetics of depletion interactions

G. A. Vliegenthart, P. Van Der Schoot

Depletion interactions between colloidal particles dispersed in a fluid medium are effective interactions induced by the presence of other types of colloid. They are not instantane…

Ab initio Monte Carlo simulations for finite-temperature properties: Application to lithium clusters and bulk liquid lithium

Sanwu Wang, Steven J. Mitchell, Per Arne Rikvold

Ab initio Monte Carlo simulations have been performed to determine the equilibrium properties of liquid lithium and lithium clusters at different temperatures. First-principles den…

Packet delay in models of data networks

Henryk Fuks, Anna T. Lawniczak, Stanislav Volkov

We investigate individual packet delay in a model of data networks with table-free, partial table and full table routing. We present analytical estimation for the average packet de…

Transient behavior in Single-File Systems

S. V. Nedea, A. P. J. Jansen, J. J. Lukkien +1

We have used Monte-Carlo methods and analytical techniques to investigate the influence of the characteristics, such as pipe length, diffusion, adsorption, desorption and reaction…

Exact results for the reactivity of a single-file system

A. P. J. Jansen, S. V. Nedea, J. J. Lukkien

We derive analytical expressions for the reactivity of a Single-File System with fast diffusion and adsorption and desorption at one end. If the conversion reaction is fast, then t…

Transverse self-fields within an electron bunch moving in an arc of a circle

Gianluca Geloni, Jan Botman, Jom Luiten +5

As a consequence of motions driven by external forces, self-fields (which are different from the static case) originate within an electron bunch. In the case of magnetic external f…

Transition from Townsend to glow discharge: subcritical, mixed or supercritical

Danijela D. Sijacic, Ute Ebert

The full parameter space of the transition from Townsend to glow discharge is investigated numerically in one space dimension in the classical model: with electrons and positive io…

A Percolative Model of Soft Breakdown in Ultrathin Oxides

C. Pennetta, L. Reggiani, Gy. Trefan

The degradation of ultrathin oxide layers in the presence of a stress voltage is modeled in terms of two antagonist percolation processes taking place in a random resistor network.…

Mesoscale simulations of surfactant dissolution and mesophase formation

P. Prinsen, P. B. Warren, M. A. J. Michels

The evolution of the contact zone between pure surfactant and solvent has been studied by mesoscale simulation. It is found that mesophase formation becomes diffusion controlled an…

Branching of negative streamers in free flight

Andrea Rocco, Ute Ebert, Willem Hundsdorfer

We recently have shown that a negative streamer in a sufficiently high homogeneous field can branch spontaneously due to a Laplacian instability, rather than approach a stationary…

Large Deviations and a Fluctuation Symmetry for Chaotic Homeomorphisms

Christian Maes, Evgeny Verbitskiy

We consider expansive homeomorphisms with the specification property. We give a new simple proof of a large deviation principle for Gibbs measures corresponding to a regular potent…

Calculation of the energy spectrum of a two-electron spherical quantum dot

Ramiro Pino, Victor M. Villalba

We study the energy spectrum of the two-electron spherical parabolic quantum dot using the exact Schroedinger, the Hartree-Fock, and the Kohn-Sham equations. The results obtained b…

Resistance and Resistance Fluctuations in Random Resistor Networks Under Biased Percolation

C. Pennetta, L. Reggiani, Gy. Trefán +1

We consider a two-dimensional random resistor network (RRN) in the presence of two competing biased percolations consisting of the breaking and recovering of elementary resistors.…
