High-Level Correlated Approach to the Jellium Surface Energy, without Uniform-Gas Input
High-Level Correlated Approach to the Jellium Surface Energy, without Uniform-Gas Input
We resolve the long-standing controversy over the metal surface energy: Density-functional methods that require uniform-electron-gas input agree with each other, but not with high-level correlated calculations such as Fermi hypernetted chain and diffusion Monte Carlo calculations that predict the uniform-gas correlation energy. Here we apply the inhomogeneous Singwi-Tosi-Land-Sj\"olander method, and …
