Lu Jeu Sham and Walter Kohn developed self-consistent equations that make density functional theory computationally useful. The Kohn-Sham equations introduce an auxiliary system of noninteracting electrons with the same ground-state electron density as the interacting system. An effective potential includes the external potential, electrostatic repulsion and an exchange-correlation functional. Solving the equations and updating the electron density iteratively gives a self-consistent state. The difficult many-electron effects remain in the exchange-correlation functional, so practical calculations still need an approximation to it.[ref]

"Lu Jeu Sham" refers to a traditional form of Chinese therapeutic massage and bodywork, often associated with the principles of Traditional Chinese Medicine (TCM). It combines elements of acupressure, stretching, and manipulation to promote relaxation, relieve pain, and enhance overall well-being. Practitioners of Lu Jeu Sham may focus on energy points along the body’s meridians to restore balance and alleviate various ailments.
