Current-density functional study of the Neon atom in a strong ultrashort magnetic field
چکیده انگلیسی

A Ne atom exposed to a strong ultrashort magnetic field of the order of 109 G109 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 >109 G>109 G.


► The work investigates a Ne atom exposed to a strong ultrashort magnetic field.
► The strength of the field is of the order of 109 G109 G that lasts for a few femtoseconds.
► A current-density functional theory (CDFT) based approach was employed.
► CDFT exhibits ‘dynamical’ effects more suitably than a TD-DFT based current-density independent approach.
