Frequently Asked Questions

What is Kohn Sham potential?

Kohn–Sham potential. In Kohn–Sham density functional theory, the total energy of a system is expressed as a functional of the charge density as. where Ts is the Kohn–Sham kinetic energy, which is expressed in terms of the Kohn–Sham orbitals as. vext is the external potential acting on the interacting system (at minimum, for a molecular system, ...

What is Kohn Sham density functional theory?

In Kohn–Sham density functional theory, the total energy of a system is expressed as a functional of the charge density as where Ts is the Kohn–Sham kinetic energy, which is expressed in terms of the Kohn–Sham orbitals as

What does TS mean in Kohn Sham?

where Ts is the Kohn–Sham kinetic energy, which is expressed in terms of the Kohn–Sham orbitals as vext is the external potential acting on the interacting system (at minimum, for a molecular system, the electron–nuclei interaction), EH is the Hartree (or Coulomb) energy and Exc is the exchange–correlation energy.

What is the Kohn Sham equation?

The Kohn–Sham equation is defined by a local effective (fictitious) external potential in which the non-interacting particles move, typically denoted as vs (r) or veff (r), called the Kohn–Sham potential.
