In this paper, the number, ratio, total and highest quantum number of thequantum coherences for 12 systems with three nuclei of non--equivalence of nucl-ear--spin quantum number I≥5/2 were computed by computer.
Through calculating associated function's operator and thermodynamic equilibration we obtained ground state magnetic induction M_(T(A,B))/M_(0(A,B)), and analyzed above physics quantities change rule along with spin quantum number and anisotropic parameter X_1,X_2,X_3.
Spin quantum number(S_a,S_b),the anisotropic parameter(X_1,X_2,X_3) and positions in the first Brillouin-Zone,and there is no influence of anisotropic parameters on magnons spectrum near the border of Brillouin-Zone.
We have also discussed the change rule of magnon energy spectrum along with anisotropic(X_1, X_2, X_3), spin quantum number(S_a, S_b), the wave vector k of main symmetrical points and lines in the first Brillouin-Zone.
The electronic energy levels of free radical and their resonance lines are calculated using a first - order approximation theory by assuming a mixed lineshape of Lorentzian and Gaussian function. The range of nuclear spin is from 1/2 to 7/2 . Up to 10 different kinds of non-equivalent nuclei are supported, but the number of equivalent nuclei, in principle, is unlimited.
A variant of electron-spin quantum computer is discussed in which a film of high dielectric constant is used to provide interaction between qubits situated in silicon.
The dynamics of a high-spin quantum system with magnetic anisotropy of the easy plane type under the action of spin-polarized current permeating this system is considered.
In a two-dimensional electron system, the combined excitation (the cyclotron spin-flip mode) associated with changes in both orbital and spin quantum numbers is investigated.
Electron-spin quantum beats in a transverse magnetic field are observed for the first time in semiconductor QDs.
Magnetic properties of the Heisenberg antiferromagnet with spin quantum numberS→∞ on the face-centered cubic lattice are studied as function of temperature and magnetic field, using molecular field approximation and Monte Carlo methods.
