Time-dependent pair density from the principle of minimum Fisher information

Research output: Contribution to journalArticle


The Euler equation for the time-dependent pair density is derived from the principle of minimum Fisher information. The same Euler equation is also derived from the recently introduced time-dependent pair density functional theory. The concept of steric effect to electron pairs is proposed and the steric pair energy is defined as the Weizsäcker kinetic energy of electron pairs.
