WebOct 15, 2024 · We have further examined the performance of new SX-DFT procedures (termed HSEB-type methods) that comprise the HSEx exchange and a (near-optimal) reparametrized B97c (c OS,0 = c SS,0 = 1, c OS,1 = -1.5, c OS,2 = -0.644, c SS,1 = -0.5, and c SS,2 = 1.10) correlation functionals. WebMay 28, 2012 · These functionals are defined by an overall fraction of Fock exchange and a length scale for exchange screening. We systematically examine this two-parameter space to assess the performance of hybrid screened exchange (sX) functionals and to determine a balance between improving accuracy and reducing the screening length, which can …
