Quantum fluid dynamics based current-density functional study of a helium atom in a strong time-dependent magnetic field

摘要: Evolution of the helium atom in a strong time-dependent (TD) magnetic field (B) strength up to 1011 G is investigated through quantum fluid dynamics (QFD) based current-density functional theory (CDFT). The TD-QFD-CDFT computations are performed numerical solution single generalized nonlinear Schrodinger equation employing vector exchange-correlation potentials and scalar density functionals that depend both on electronic charge-density current-density. results compared with obtained from B-TD-QFD-DFT approach (based conventional TD-DFT) under similar constraints but only potential dependent only. approach, at particular TD field-strength, yields charge- current-densities as well resembling time-independent studies involving static (time-independent) fields. However, along energy differ significantly using particularly field-strengths >109 G, representing dynamical effects field. work concludes when subjected order TD-DFT differs “dynamically” CDFT computational constraints.
