Schematics of a, b crystal structure, c, d energy profile, and e, f band structure from insulating (left plane) to a metallic (right plane) state under the illumination of a THz pulsed laser as well as displacement patterns associated with the excited breathing (Ag) and pumped Infrared (Bu) phonon modes (middle plane).
