Hydromagnetic transverse instability of two highly viscous fluid-particle flows with finite ion Larmor radius correctionsThe European Physical Journal D - Atomic, Molecular, Optical and Plasma Physics - Tập 23 - Trang 391-403 - 2003
M.F. El-Sayed
A linear analysis of the combined effect of viscosity, finite ion Larmor radius and suspended particles on Kelvin-Helmholtz instability of two superposed incompressible fluids in the presence of a uniform magnetic field is carried out. The magnetic field is assumed to be transverse to the direction of streaming. A general dispersion relation for such a configuration has been obtained using appropr...... hiện toàn bộ
First principle study on the bonding mechanism of nanoring structure Ga8As8The European Physical Journal D - Atomic, Molecular, Optical and Plasma Physics - Tập 34 - Trang 47-50 - 2005
L. Z. Sun, X. S. Chen, X. H. Zhou, Y. L. Sun, Zh. J. Quan, Wei Lu
The stable ring structure of Ga8As8 has been
found by the first principle calculations previously. Here we use
the full-potential linearized augmented plane wave (FP-LAPW)
method within the framework of the density functional approach to
investigate the electronic structure and bonding mechanism of the
ring structure. The stable and equilibrium ring structure is
confirmed again and the relationshi...... hiện toàn bộ
The hyperfine structure of the and states and 5) for the lithium isoelectronic sequenceThe European Physical Journal D - Atomic, Molecular, Optical and Plasma Physics - Tập 2 - Trang 21-27 - 1998
X.-X. Guan, Z.-W. Wang
The non-relativistic hyperfine structure parameters, the Fermi contact, the spin-dipolar, the orbital and the electronic quadrupole terms, of the lithium-like ground state and low-lying states,
and
(n
=2, 3, 4, and 5), are calculated with the full core plus correlation (FCPC) wave functions. With the 794- and 1185-term Sla...... hiện toàn bộ
Studies of bosons in optical lattices in a harmonic potentialThe European Physical Journal D - Atomic, Molecular, Optical and Plasma Physics - Tập 42 - Trang 309-316 - 2007
R. Ramakumar, A. N. Das, S. Sil
We present a theoretical study of Bose condensation and specific heat
of non-interacting bosons in finite lattices in harmonic potentials in
one, two, and three dimensions. We numerically diagonalize
the Hamiltonian to obtain the energy levels of the systems.
Using the energy levels thus obtained, we investigate the
temperature dependence, dimensionality effects, lattice size
dependence, and evo...... hiện toàn bộ
Benchmark for two-photon ionization of atoms with generalized Sturmian functionsThe European Physical Journal D - Atomic, Molecular, Optical and Plasma Physics - Tập 70 - Trang 1-11 - 2016
Antonio I. Gómez, Gustavo Gasaneo, Darío M. Mitnik, Marcelo J. Ambrosio, Lorenzo U. Ancarani
The description with traditional methods of the single or multiple ionization of atoms
and molecules by two or more successive photons requires some special treatment.
Difficulties occur when a spatially non-decaying driven term appears in the
Schrödinger-like non-homogeneous equation for the scattering wave function. We propose
using the intrinsic physical and mathematical properties of generali...... hiện toàn bộ
Stability of a plasma foil in the radiation pressure dominated regimeThe European Physical Journal D - Atomic, Molecular, Optical and Plasma Physics - Tập 55 - Trang 399-405 - 2009
F. Pegoraro, S. V. Bulanov
The stability of a thin plasma foil accelerated to relativistic velocities by the radiation pressure of an ultra high intensity electromagnetic pulse is investigated. The effects of the onset of a Rayleigh-Taylor-like instability are discussed in the context of the ion acceleration process during the interaction of the laser pulse with the plasma. It is stressed that the experimental study of this...... hiện toàn bộ
Formation and characterization of high-density Fe cluster-assembled films with soft magnetic behaviorsThe European Physical Journal D - Atomic, Molecular, Optical and Plasma Physics - Tập 34 - Trang 173-176 - 2005
D. L. Peng, H. Yamada, K. Sumiyama, T. Uchida, T. Hihara
High-density, magnetically soft Fe cluster-assembled
films were obtained at room temperature by an energetic cluster deposition.
Size-monodispersed Fe clusters with the mean cluster size d = 9, 13 and 16 nm
were produced using a plasma-gas-condensation technique. Ionized clusters in
cluster beam were accelerated electrically and deposited onto the substrate
together with neutral clusters from...... hiện toàn bộ
