摘要

This study presents SALMON VR, a visualization program designed to visualize the time evolution of electronic density changes and vector potentials in virtual reality (VR) space. The time-series electronic density data computed by SALMON are stored in CUBE format. SALMON VR processes these data to construct isosurfaces of electronic density variations and two-dimensional representations of vector potentials. Equipped with a user-friendly interface using VR technology, the program is available in two versions: one for the Meta Quest 3 head-mount display (Meta Platforms Inc., California) and one for PCs. Atoms are displayed as spheres of different sizes and colors according to their elemental properties. This visual representation facilitates a deeper understanding of the complex interactions between light and electrons. Users can easily manipulate the isosurface values, speed of animation, and color map of the vector potential. SALMON VR will enable researchers and educators to enhance their understanding of physical phenomena and improve engagement in learning environments.
