This implies that no matter what the complex four-coordinates and four-velocities of the particle are at the time moments greater than \(\tau \) when it moves backward in time, it should arrive at the initial time \(\tau \) with the real four-coordinate \(x_\tau \). As far as \...
This is probably due to strong displacements of the Mn atoms and the neighboring Te atoms in the vibrations of \({A}_{1g}^{{\prime} }\) and \({A}_{2u}^{{\prime} }\) modes as these atoms host the majority of magnetic moments in the system. For the \({A}_{1g}^{\prime\...

Presents a study that developed a model calculation on a large periodic unit cell of amorphous iron (Fe) containing 200 atoms to determine the distribution of its local orbital moments.

Compare the moments of inertia of ring A and B. (A) IA>IB. (B) IA<IB. (C) IA = IB. (D) can not determine. (C) 9. The rotation axis is horizontal. At the initial time, the rod is at rest horizontally. Then the rod rotates to the vertical position. In this process, which...
We further study the magnetic and electronic properties of such hybrid nanostructures and show that triangular carbon islands embedded into BN sheets possess magnetic moments, which can be switched on and off by electrically charging the structure. 展开 ...
The local magnetic moments of X atoms amount to about 99.9% of the total magnetic moment, while those of In atoms are merely 0.1%. The IR and Raman spectra of \\\( {m In}_{m}X_{n}\\\) clusters exhibit similarity for \\\( X={m Se}\\\) and Te with an exception of \\\(...
In other words, the retrospective description can for a small number of moments say the exact outcomes. On the other hand, the disadvantage is that a single retrospective description cannot be used to make any quantitative predictions. Only a sufficiently large set of retrospective descriptions may...
Intriguing electronic and magnetic properties of boron nitride (BN) layer with noble metal (Pd, Pt, Ag and Au) doping are obtained by first-principles calculations. Adsorbed Pd (or Pt) reduces the bandgap of BN sheet owing to the induction of impurity states. The unpaired electrons in the ...
