Question

When using AIMPAC, the flux of this quantity’s gradient is taken to be zero when defining a surface. Perdew et al. proposed a framework for ordering methods of determining this quantity based on chemical accuracy nicknamed “Jacob’s ladder.” In a technique that calculates this quantity, exchange-correlation energy can be estimated by approximations like the GGA (10[1])and LDA. Because a system’s ground state energy is uniquely dependent on this quantity, determining the distribution of this quantity for a chemical is equivalent to “solving” its structure according to the Hohenberg–Kohn theorem. “Functionals” of this quantity are used to model chemicals in DFT. (10[1])For 10 points, (10[1])name this quantity that describes a molecule’s negative charge per unit volume. ■END■
