JuNoLo - Jülich Non Local code for parallel calculation of vdW-DF nonlocal density functional theory

چکیده
Nowadays the state of the art Density Functional Theory (DFT) codes are based on local (LDA) or semilocal (GGA) energy functionals. Recently the theory of a truly nonlocal energy functional has been developed. It has been used mostly as a post DFT calculation approach, i.e. by applying the functional on the charge density calculated using any standard DFT code, thus obtaining a new improved value for the total energy of the system. Nonlocal calculation is computationally quite expensive and scales as N where N is the number of points in which charge density is defined, and a massively parallel calculation is essential for a wider applicability of the new approach. In this article we present a code which acomplishes this goal. PACS: 71.15.-m; 71.15.Mb; 71.45.Gm

Interpretation of van der Waals density functionals
The nonlocal correlation energy in the van der Waals density functional (vdW-DF) method can be interpreted in terms of a coupling of zero-point energies of characteristic modes of semilocal exchange-correlation (xc) holes. These xc holes reflect the internal functional in the framework of the vdW-DF method. We explore the internal xc hole components, showing that they share properties with thos...
متن کاملExchange functional that tests the robustness of the plasmon description of the van der Waals density functional
Is the plasmon description within the nonlocal correlation of the van der Waals density functional by Dion and coworkers (vdW-DF) robust enough to describe all exchange-correlation components? To address this question, we design an exchange functional based on this plasmon description as well as recent analysis on exchange in the large-s regime. In the regime with reduced gradients s = |∇n|/2nk...
متن کاملRole of van der Waals bonding in the layered oxide V2O5: First-principles density-functional calculations
Sparse matter is characterized by regions with low electron density and its understanding calls for methods to accurately calculate both the van der Waals vdW interactions and other bonding. Here we present a first-principles density-functional theory DFT study of a layered oxide V2O5 bulk structure which shows charge voids in between the layers and we highlight the role of the vdW forces in bu...
متن کاملvan der Waals density functionals built upon the electron-gas tradition: facing the challenge of competing interactions.
The theoretical description of sparse matter attracts much interest, in particular for those ground-state properties that can be described by density functional theory. One proposed approach, the van der Waals density functional (vdW-DF) method, rests on strong physical foundations and offers simple yet accurate and robust functionals. A very recent functional within this method called vdW-DF-c...
متن کاملnoloco: An efficient implementation of van der Waals density functionals based on a Monte-Carlo integration technique
The treatment of van der Waals interactions in density functional theory is an important field of ongoing research. Among different approaches developed recently to capture these non-local interactions, the van der Waals density functional (vdW-DF) developed in the groups of Langreth and Lundqvist is becoming increasingly popular. It does not rely on empirical parameters, and has been successfu...
