We study the C2 Ruijsenaars-Schneider model with interaction potential of trigonometric type. The Lax pairs for the model with and without spectral parameters a
The theoretical study of PuOn+(n=l,2,3) using a density functional method shows that PuO+ (X6∑-) and PuO2+ (X5∑-, 7∑-, 9∑-) ions are stable, and the PuO3+ (4∑+,
The thermodynamics of the vortex lattice of high-temperature superconductors has been studied by solving the generalized Ginzburg-Landau equations derived micro
The temperature dependence of lattice constants a and c of intermetallic compounds RMn2Ge2 (R=Sm, Gd) is measured in the temperature range 10-800K by using the
We take into account the two-photon process and generalize the Jaynes-Cummings (JC) model to the case of atomic level degenerate in the projections of the angul
In this paper, we report on the structural properties and superconductivity of Mg(B1-xCx)2 compounds. PowderX-ray diffraction results indicate that the samples
We present a new methodology for studying the mean-square exponential stability and instability of nonlinear nonholonomic systems under disturbance of Gaussian
The demagnetization curve as a function of intensity of the inter-grain exchange interaction was calculated for single-phase nanocrystalline Nd-Fe-B magnets by
