Abstract

Ultrahigh intensity lasers are proven to be particularly suitable for ion acceleration to energies above hundreds of keV and even in the multi MeV range, due to their interaction with either planar thin solid foils, or spherically symmetric targets. With reference to these problems, a quasistationary model is developed, where the Poisson equation for the electrostatic potential distribution at the sharp solid target-vacuum interface is solved for a nonrelativistic Maxwellian distribution of trapped electrons. Analytical solutions are given and ion acceleration in the relevant electrostatic field configurations is discussed.

A monotonicity preserving conservative sharp interface flow solver for high density ratio two-phase flows

Journal Article Le Chenadec, Vincent, E-mail: vlechena@stanford.edu ; Pitsch, Heinz ; Institute for Combustion Technology, RWTH Aachen, Templergraben 64, 52056 Aachen - Journal of Computational Physics

This paper presents a novel approach for solving the conservative form of the incompressible two-phase Navier–Stokes equations. In order to overcome the numerical instability induced by the potentially large density ratio encountered across the interface, the proposed method includes a Volume-of-Fluid type integration of the convective momentum transport, a monotonicity preserving momentum rescaling, and a consistent and conservative Ghost Fluid projection that includes surface tension effects. The numerical dissipation inherent in the Volume-of-Fluid treatment of the convective transport is localized in the interface vicinity, enabling the use of a kinetic energy conserving discretization away from the singularity.

Nonlinear electrostatic oscillations in a sharp plasma interface

Journal Article Haas, F. ; Shukla, P. K. - AIP Conference Proceedings

We revisit a generalized nonlinear Schroedinger equation derived by Stenflo and Gradov, describing electrostatic oscillations in a sharp plasma interface. A Madelung decomposition is used to deduce a Sagdeev potential associated to an autonomous one-dimensional Hamiltonian system, whose solutions are all periodic. A conservation law preventing singularities (under suitable boundary conditions and initial wave profile) is derived. In the particular case where some of the nonlinearities can be neglected, the model is shown to be equivalent to the free-particle Schroedinger equation.

Reduction in the interface-states density of metal-oxide-semiconductor field-effect transistors fabricated on high-index Si (114) surfaces by using an external magnetic field

Journal Article Molina, J., E-mail: jmolina@inaoep.mx ; De La Hidalga, J. ; Gutierrez, E. - Journal of Applied Physics

After fabrication of Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) devices on high-index silicon (114) surfaces, their threshold voltage (Vth) and interface-states density (Dit) characteristics were measured under the influence of an externally applied magnetic field of B = 6 μT at room temperature. The electron flow of the MOSFET's channel presents high anisotropy on Si (114), and this effect is enhanced by using an external magnetic field B, applied parallel to the Si (114) surface but perpendicular to the electron flow direction. This special configuration results in the channel electrons experiencing a Lorentzian force which pushes the electrons closer to the Si (114)-SiO{sub 2} interfacemore »« less

Difference in distribution of membrane proteins between low- and high-density secretory granules in parotid acinar cells

Journal Article Fujita-Yoshigaki, Junko ; Katsumata, Osamu ; Matsuki, Miwako ; ... - Biochemical and Biophysical Research Communications

Secretory granules (SGs) are considered to be generated as immature granules and to mature by condensation of their contents. In this study, SGs of parotid gland were separated into low-, medium-, and high-density granule fractions by Percoll-density gradient centrifugation, since it was proposed that the density corresponds to the degree of maturation. The observation with electron microscopy showed that granules in the three fractions were very similar. The average diameter of high-density granules was a little but significantly larger than that of low-density granules. Although the three fractions contained amylase, suggesting that they are all SGs, distribution of membrane proteinsmore »« less

The phase-field method in the sharp-interface limit: A comparison between model potentials

Journal Article Fabbri, M. ; Voller, V.R. - Journal of Computational Physics

The phase-field (PF) method for solidification phenomena is an open formulation based on a free-energy functional. Two common choices for the PF potential, here referred to briefly as the Caginalp and Kobayashi models, are compared with respect to their numeric results within the classical sharp-interface limit. Both qualitative and quantitative behavior are addressed, and an assessment of the computational effort required to approximate a sharp-interface problem is made. It is shown that the specific form of the free-energy potential does have a strong influence on the convergence of the PF results to their sharp-interface limit. Compliance of the PF solutionsmore »« less
