export_wannier90.h

Purpose

Wannier90 format export functions for HWAVE mode. These functions export geometry and interaction data in a format compatible with Wannier90-style tight-binding models.

Important

This header is only available when _HWAVE is defined at compile time. The functions are wrapped in #if defined(_HWAVE) preprocessor conditionals.

Source reference: src/export_wannier90.h

Public Types

None.

Public Macros/Constants

EXPORT_WANNIER90_INCLUDED

Include guard macro.

Public Functions

void ExportGeometry(struct StdIntList *StdI)

Exports lattice geometry information in Wannier90 format.

Parameters:

  • StdI – Pointer to the configuration structure

Writes geometry data including lattice vectors and site positions. Output format details are unspecified in the current code.

Availability: Only when _HWAVE is defined.

void ExportInteraction(struct StdIntList *StdI)

Exports interaction parameters in Wannier90 format.

Parameters:

  • StdI – Pointer to the configuration structure

Writes hopping and interaction terms. Output format details are unspecified in the current code.

Availability: Only when _HWAVE is defined.

Ownership and Lifetime Rules

  • Functions do not allocate or free the StdI structure.

  • Output files are created/written by these functions; file handles are managed internally.

Error Handling

Unspecified in the current code.

Thread / MPI Safety

Unspecified in the current code.
