Time-Dependent Density-Functional Theory for Trapped Strongly-Interacting Fermionic Atoms
Yeong E. Kim, Alexander L. Zubarev
Abstract
The dynamics of strongly interacting trapped dilute Fermi gases (dilute in the sense that the range of interatomic potential is small compared with inter-particle spacing) is investigated in a single-equation approach to the time-dependent density-functional theory. Our results are in good agreement with recent experimental data in the BCS-BEC crossover regime. It is also shown that the calculated corrections to the hydrodynamic approximation may be important even for systems with a rather large number of atoms.
