pyGWBSE: a high throughput workflow package for GW-BSE calculations

نویسندگان

چکیده

Abstract We develop an open-source python workflow package, py GWBSE to perform automated first-principles calculations within the GW-BSE (Bethe-Salpeter) framework. is a many body perturbation theory based approach explore quasiparticle (QP) and excitonic properties of materials. GW approximation accurately predicts bandgaps materials by overcoming bandgap underestimation issue more widely used density functional (DFT). BSE formalism produces absorption spectra directly comparable with experimental observations. package achieves complete automation entire multi-step computation, including convergence tests several parameters that are crucial for accuracy these calculations. integrated Wannier90 , generate QP bandstructures, interpolated using maximally-localized wannier functions. also enables creation databases metadata data, properties, which can be extremely useful future material discovery studies in field ultra-wide semiconductors, electronics, photovoltaics, photocatalysis.

LabFlow-1: A Database Benchmark for High-Throughput Workflow Management

Workkow management is a ubiquitous task faced by many organizations, and entails the coordination of various activities. This coordination is increasingly carried out by software systems called work-ow management systems (WFMS). An important component of many WFMSs is a DBMS for keeping track of workkow activity. This DBMS maintains an audit trail, or event history, that records the results of ...

Grid Workflow Software for a High-Throughput Proteome Annotation Pipeline

The goal of the Encyclopedia of Life (EOL) Project is to predict structural information for all proteins, in all organisms. This calculation presents challenges both in terms of the scale of the computational resources required (approximately 1.8 million CPU hours), as well as in data and workflow management. While tools are available that solve some subsets of these problems, it was necessary ...

g_mmpbsa - A GROMACS Tool for High-Throughput MM-PBSA Calculations

Molecular mechanics Poisson-Boltzmann surface area (MM-PBSA), a method to estimate interaction free energies, has been increasingly used in the study of biomolecular interactions. Recently, this method has also been applied as a scoring function in computational drug design. Here a new tool g_mmpbsa, which implements the MM-PBSA approach using subroutines written in-house or sourced from the GR...
