The set of non-linear differential equations which describes the kink chain oscillating in an atmosphere of continuously distributed paraelastic (interstitials) or isotropic defects and, in addition, decorated by a dragging point defect at the midpoint, is solved numerically after introducing a novel scaling and re-normalization procedure. The internal friction coefficient obtained indicates the existence of two separate peaks, the decoration peak and the parent peak, which are directly related to the selectively localized point defect dragging and the smeared-out paraelastic or isotropic defects atmosphere, respectively.

ACCURATE COMPUTATION OF THE ENERGY-SPECTRUM FOR POTENTIALS WITH MULTIMINIMA
Taşeli, Hasan (Wiley, 1993-01-01)
The eigenvalues of the Schrodinger equation with a polynomial potential are calculated accurately by means of the Rayleigh-Ritz variational method and a basis set of functions satisfying Dirichlet boundary conditions. The method is applied to the well potentials having one, two, and three minima. It is shown, in the entire range of coupling constants, that the basis set of trigonometric functions has the capability of yielding the energy spectra of unbounded problems without any loss of convergence providin...
Calculation of Magnetization and Magnetic Susceptibility Close to Magnetic Phase Transitions in (CH3)2NH2FeIIINiII(HCOO)6 and (CH3)2NH2FeIIICuII(HCOO)6
Yurtseven, Hasan Hamit (Springer Science and Business Media LLC, 2020-01-01)
We study the temperature and magnetic field dependence of the magnetization (M) and the inverse susceptibility (chi(-1)) in the metal-organic frameworks, in particular, for (CH3)(2)(NH2FeNiII)-Ni-III(HCOO)(6) (DMFeNi) and (CH3)(2)(NH2FeCuII)-Cu-III(HCOO)(6) (DMFeCu) close to their magnetic phase transitions. The Landau phenomenological model is employed to analyze the experimental data for the M(T, H) from the literature and to calculate chi(-1)(T, H) of DMFeNi and DMFeCu. Our results indicate that the ther...
Multiphoton core ionization dynamics of polyatomic molecules
Toffolı, Danıele; Decleva, Piero (IOP Publishing, 2013-07-28)
The two-photon core ionization dynamics of gas-phase methane, carbon monoxide and nitrogen have been studied with a recent implementation of the lowest order perturbation theory in the framework of density functional theory and a multicentric basis set expansion of bound and scattering states. Ionization cross sections and angular asymmetry parameters have been calculated for the case of a single radiation beam and for both linear and circular light polarizations in the fixed nuclei approximation. Expected ...
Ground-state properties and collective excitations in a 2D Bose-Einstein condensate with gravity-like interatomic attraction
Keleş, Ahmet; Tanatar, B. (Springer Science and Business Media LLC, 2008-02-01)
We study the ground-state properties of a Bose-Einstein condensate (BEC) with the short-range repulsion and gravitylike 1/r interatomic attraction in two-dimensions (2D). Using the variational approach, we obtain the ground-state energy and show that the condensate is stable for all interaction strenghts in 2D. We also determine the collective excitations at zero temperature using the time-dependent variational method. We analyze the properties of the Thomas-Fermi-gravity (TF-G) and gravity (G) regimes.
An algebraic method for the analytical solutions of the Klein-Gordon equation for any angular momentum for some diatomic potentials
Akçay, Hüseyin; Sever, Ramazan (IOP Publishing, 2014-01-01)
Analytical solutions of the Klein-Gordon equation are obtained by reducing the radial part of the wave equation to a standard form of a second-order differential equation. Differential equations of this standard form are solvable in terms of hypergeometric functions and we give an algebraic formulation for the bound state wave functions and for the energy eigenvalues. This formulation is applied for the solutions of the Klein-Gordon equation with some diatomic potentials.
