# Wannier90 Tight-Binding

## Purpose

Provides expert guidance on Wannier90 for constructing maximally localized Wannier functions and tight-binding models from DFT calculations.

## Capabilities

- Wannierization from DFT
- Band interpolation
- Berry phase calculations
- Topological invariant computation
- Transport property modeling
- Interface with DFT codes (VASP, QE)

## Usage Guidelines

1. **Wannierization**: Set up Wannier90 input from DFT calculations
2. **Disentanglement**: Configure frozen and disentanglement windows
3. **Band Interpolation**: Generate interpolated band structures
4. **Topology**: Calculate Berry phases and topological invariants
5. **Transport**: Interface with transport codes
