Improved Lieb-Oxford exchange-correlation inequality with a gradient correction
Improved Lieb-Oxford exchange-correlation inequality with a gradient correction
We prove a Lieb-Oxford-type inequality on the indirect part of the Coulomb energy of a general many-particle quantum state, with a lower constant than the original statement but involving an additional gradient correction. The result is similar to a recent inequality of Benguria et al. [Int. J. Quantum Chem. 112, …
