Comparing the relativistic and nonrelativistic frame works, we study the effect of the relativistic center-of-mass vector on the electric polarizability of a co
Temperature dependence of the pair-breaking critical current density of MgB2, jd(T), is studied using a two-band Ginzburg-Landau theory. The results are shown t
A scheme is presented for generating W states for three o()four trapped ions in thermal motion. The scheme works in the regime, where the Rabi frequency of the
