A second-generation range-separated hybrid van der Waals density functional

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Vivekanand Shukla, Yang Jiao, Jung-Hoon Lee, Elsebeth Schroder, Jeffrey B. Neaton | Summary: We define, test, and illustrate use of a range-separated (screened) hybrid, termed vdW-DF2-ahbr and abbreviated AHBR, that uses the second-generation nonlocal-correlation formulation [PRB {bf 82}, 081101(R) (2010)] within the van der Waals density […]

Accurate non-empirical range-separated hybrid van der Waals density functional for complex molecular problems, solids, and surfaces

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Vivekanand Shukla, Yang Jiao, Jung-Hoon Lee, Elsebeth Schroder, Jeffrey B. Neaton | Summary: We introduce a new, general-purpose, range-separated hybrid van der Waals density ph{functional, termed vdW-DF-ahbr,} within the non-empirical vdW-DF method [JPCM 32, 393001 (2020)]. It combines correlation from vdW-DF2 with a screened Fock exchange […]

An extended mixed finite element method for elliptic interface problems

Kavli Affiliate: Feng Wang | First 5 Authors: Pei Cao, Jinru Chen, Feng Wang, , | Summary: In this paper, we propose an extended mixed finite element method for elliptic interface problems. By adding some stabilization terms, we present a mixed approximation form based on Brezzi-Douglas-Marini element space and the piecewise constant function space, and […]
