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 Slater-type expansions, the Fermi contact interactions of the
and states in are... 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 evolu... hiện toàn bộ
Influence of semiclassical plasma on the energy levels and radiative transitions in highly charged ionsThe European Physical Journal D - Atomic, Molecular, Optical and Plasma Physics - Tập 71 - Trang 1-7 - 2017
Hong-Wei Hu, Zhan-Bin Chen, Wen-Cong Chen, Xiao-Bin Liu, Nian Fu, Kai Wang
Considering the quantum effects of diffraction and the collective screening
effects, the potential of test charge in semiclassical plasmas is derived. It is
generalized exponential screened Coulomb potential. Using the Ritz variational
method incorporating this potential, the effects of semiclassical plasma on the
energy levels and radiative transitions are investigated systematically, taking
high... 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
generaliz... 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
