Area of Science:

• Condensed matter physics
• Materials science
• Computational chemistry

Background:

• Vibrational inelastic neutron scattering (vINS) spectroscopy is crucial for understanding complex materials.
• Interpreting vINS spectra often relies on theoretical simulations, typically using ab initio methods to derive force constants.
• Current workflows face challenges due to large data volumes, computational expense, and poor integration between simulation and analysis software.

Purpose of the Study:

• To present Euphonic, a novel software package designed to simplify and accelerate the analysis of vINS spectra.
• To provide a computationally efficient and user-friendly tool that bridges the gap between theoretical calculations and experimental data.

Main Methods:

• Development of the Euphonic software package.
• Integration capabilities with ab initio codes for direct force constant matrix output.
• Designed for seamless interfacing with experimental data analysis software.

Main Results:

• Euphonic offers a robust and computationally efficient solution for vINS spectral interpretation.
• The package streamlines the workflow by directly interfacing with ab initio outputs.
• Facilitates direct comparison between simulated and experimental vINS spectra.

Conclusions:

• Euphonic significantly enhances the efficiency and accessibility of vINS spectral analysis.
