摘要：
A Ne atom exposed to a strong ultrashort magnetic field of the order of 10(9) G that lasts for a few femtoseconds is investigated through a current-density functional theory (CDFT) based approach employing a vector exchange-correlation potential that depends on the electronic charge-density as well as on the current-density of the atom. The CDFT based approach yields time-dependent electronic charge- and current-density, along with the exchange-correlation potential and energy, significantly different from that obtained using a current-density independent approach, in particular, at the field-strengths > 10(9) G.
