Computational simulation of type-II superconductivity including pinning phenomena
(American Physical Society, 1995-06-15)
A flexible tool, based on the finite-element method, for the computational simulation of vortex phenomena in type-II superconductors has been developed. These simulations use refined or newly developed phenomenological ...
Scanning near-field optical microscopy utilizing silicon nitride probe photoluminescence
(AIP Publishing, 2005-11)
We describe a simple method for performing high-resolution scanning near-field optical microscopy (SNOM). A commercial Si3N4 tip is illuminated by an intense light source, which causes the tip to emit redshifted (inelastically ...
Competition between multiple totally asymmetric simple exclusion processes for a finite pool of resources
(American Physical Society, 2009-09)
Using Monte Carlo simulations and a domain-wall theory, we discuss the effect of coupling several totally asymmetric simple exclusion processes (TASEPs) to a finite reservoir of particles. This simple model mimics directed ...
Microscopic study of the 2/5 fractional quantum Hall edge
(American Physical Society, 2011-12-09)
This paper reports on our study of the edge of the 2/5 fractional quantum Hall state, which is more complicated than the edge of the 1/3 state because of the presence of edge sectors corresponding to different partitions ...
Phenomenology of aging in the Kardar-Parisi-Zhang equation
(American Physical Society, 2012-03-27)
We study aging during surface growth processes described by the one-dimensional Kardar-Parisi-Zhang equation. Starting from a flat initial state, the systems undergo simple aging in both correlators and linear responses, ...
Origin of scintillation in cerium_doped oxide crystals
(AIP Publishing, 1995-05)
We propose here a model of the scintillation from complex oxide single crystalsdoped with Ce3+ ions to explain the correlation observed between scintillation light yield and intrinsic luminescence of the matrix.
Lagrangian and energy forms for retrieving the impulse response of the Earth due to random electromagnetic forcing
(American Physical Society, 2011-08-10)
We distinguish between trivial and nontrivial differences in retrieving the real or imaginary parts of the Green's function. Trivial differences come from different Green's function definitions. The energy and Lagrangian ...
Infrared studies of hole-plasmon excitations in heavily-doped p-type MBE-grown GaAs : C
(American Physical Society, 2000-08-15)
Infrared reflectivity measurements (200-5000 cm(-1)) and transmittance measurements (500-5000 cm(-1)) have been carried out on heavily-doped GaAs:C films grown by molecular-beam epitaxy. With increasing carbon concentration, ...
Field-induced vacancy localization in a driven lattice gas: Scaling of steady states
(American Physical Society, 2000-01)
With the help of Monte Carlo simulations and a mean-field theory, we investigate the ordered steady-state structures resulting from the motion of a single vacancy on a periodic lattice which is filled with two species of ...
Photogeneration action spectroscopy of neutral and charged excitations in films of a ladder-type poly(para-phenylene)
(American Physical Society, 1999-04-19)
The photogeneration quantum efficiency action spectra of long-lived neutral and charged excitations in films of a ladder-type poly(para-phenylene) were measured. We found that both tripler and polaron action spectra show, ...
