<正> The microscopic recollision dynamics in strong-field nonsequential double ionization of Ar atoms is investigatedusing three-dimensional classical ensembles
<正> Based on the strong magnetic anisotropy along the symmetry of the crystal,we construct a U(2) non-Abeliangauge potential for the molecular nanomagnet Mn2 b
<正> The properties of the high spin states of the neutron-rich 98-102Sr and 100-104Zr isotopes have been studiedusing the projected shell model.In particular,t
