Abstract
|
|
|
|
The kinetic energy density t(G) (r), where G denotes the gradient form (delpsi)(2), is known to be a functional of the ground-state density rho(r), but the functional remains unknown. For an arbitrary number of closed shells in a bare Coulomb field, an exact first-order differential equation is derived giving t(G)(r) solely in terms of s-state information. Numerical illustrations are given of the main analytical results. |
