Manipulation and post-processing of DFT output and creating tight-binding models for NEGF transport
Project description
sisl
Copyright Nick R. Papior 2023
sisl is an open-source easy-to-use density functional theory API framework to post-analyse density functional theory codes output as well as providing tight-binding calculation capabilities. It couples to a wide range of density functional theory codes and has a high connection with LCAO codes such as Siesta. The tight-binding matrices can be used in non-equilibrium Green function calculations with TBtrans as a backend. API for creating publication ready graphs and images.
Features
- Simple command-line interface: To extract or quickly plot calculation output
- Tight-binding API: Easily create (non-) orthogonal tight-binding matrices and do electronic structure analysis
- Manipulation of sparse matrices: Extract, replace, append matrices and sub-matrices to one another
- Post analyse DFT simulations: Post-process LCAO Hamiltonians by doing (projected) density of states, inverse participation ratio and many more
- Post analyse NEGF simulations: Effectively create and post-analyse NEGF output from TBtrans
- Real-space grid analysis: Perform mathematical operations on DFT real-space grid outputs, spin-density differences and wavefunction plots
- Conversion of geometries and real-space grid: Easy conversion of geometry files and real-space grid file formats (cube, xsf, etc.)
- User contributed toolboxes: Users may contribute toolboxes for sharing methodologies
- Interoperability with other codes: ASE and pymatgen
- and many more features
