EXCEED-DM: DFT-Computed Electronic Wave Functions for Silicon and Germanium

Wave function coefficients for silicon and germanium computed on a 10x10x10 uniform k mesh. The data includes results both with and without all-electron reconstruction, generated by Sinéad M. Griffin at Lawrence Berkeley National Laboratory. It is intended for use with the EXCEED-DM framework to compute electronic excitation rates induced by dark matter.

Use Cases

• Benchmarking dark matter-electron scattering models based on provided wave function coefficients.
• Comparing electronic structure calculations with and without all-electron reconstruction for silicon and germanium.
• Training machine learning models to predict electronic excitation rates using the computed wave functions.

Strengths

• Wave functions are provided for two distinct elemental semiconductors, silicon and germanium.
• Data includes results both with and without all-electron reconstruction for comparison.
• Calculations are performed on a defined 10x10x10 uniform k mesh.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
