We construct multi-parametric rational solutions to the KdV equation. For this, we use solutions in terms of exponentials depending on several parameters and take a limit when one of these parameters goes to 0. Here we present degenerate rational solutions and give a result witho...

In the form of two quasi-particles coupled to a core described by the IBM-1 and Triaxil Rotor models, the high-spin states of the Ba and Ce isotopes are studied. Bands based on both (vh11/2)-2 and (configurations are considered, which is found to be appropriate for this region to...

We follow theoretically the motion of the sodium atoms in vapor state under the influence of a laser mode in (1 + 1) D, which is achieved by introducing different optical filters. In the Dirac interaction representation, the equations of motion are represented via the Bloch form...
