Extended Thomas-Fermi model at finite temperature
Journal Article
·
· Phys. Rev. Lett.; (United States)
We derive for the first time second-order gradient corrections to the Thomas-Fermi kinetic-energy and entropy density functionals for a fermion system at finite temperature. Density variational calculations for a heated nucleus with a Skyrme interaction lead to excellent agreement with results of Hartree-Fock calculations.
