The vibration states of transition molecule S2O, including both bending and stretching vibrations, arestudied in the framework of dynamical symmetry groups U1(4
We discuss and analyze absorption-dispersion response for the probe field in a typical four-level atomic system with vacuum-induced coherence (VIC) arising from
In this letter,starting from a Backlund transformation,a general solution ofa(2+1)-dimensional integrable system is obtained by using the new variable separatio
The elastic constants of superconducting MgB2 are calculated using a molecular dynamics method (MD)with shell model. The lattice parameters, five independent el
