Effect of spin-orbit interaction on heterojunction band discontinuities
The effect of spin-orbit interaction is included in the linear combination of atomic orbitals calculation of heterojunction band discontinuities. It is found that spin-orbit interaction is not negligible when the atomic number of the constituent atoms exceeds about 40. The effect of spin-orbit interaction as well as some interesting observations and their implications are briefly discussed
Diagnostics of macroscopic quantum states of Bose-Einstein condensate in double-well potential by nonstationary Josephson effect
We propose a method of diagnostic of a degenerate ground state of Bose
condensate in a double well potential. The method is based on the study of the
one-particle coherent tunneling under switching the time-dependent weak
Josephson coupling between the wells. We obtain a simple expression that allows
to determine the phase of the condensate and the total number of the particles
in the condensate from the relative number of the particles in two wells
measured before the Josephson coupling is switched on and
after it is switched off. The specifics of the application of the method in the
cases of the external and the internal Josephson effect are discussed.Comment: 3 page
Low-lying states in even Gd isotopes studied with five-dimensional collective Hamiltonian based on covariant density functional theory
Five-dimensional collective Hamiltonian based on the covariant density
functional theory has been applied to study the the low-lying states of
even-even Gd isotopes. The shape evolution from Gd to
Gd is presented. The experimental energy spectra and intraband
transition probabilities for the Gd isotopes are reproduced by the
present calculations. The relative ratios in present calculations are
also compared with the available interacting boson model results and
experimental data. It is found that the occupations of neutron
orbital result in the well-deformed prolate shape, and are essential for Gd
isotopes.Comment: 11pages, 10figure
