On the kinetic energy of unitary Fermi gas in a harmonic trap
arXiv:0906.1239 · doi:10.1209/0295-5075/87/33001
Abstract
We have considered the orbital-free approximation of the kinetic energy functional to investigate the zero temperature properties of dilute harmonically trapped two component Fermi gas at unitarity. It is shown that our approach provides a realible and inexpensive method to study superfluid strongly interacting dilute Fermi gases.
