We have investigated pressurized VO₂ using optical pump – THz probe spectroscopy. Distinct pump-probe signals and an excitation threshold are observed even in the metallic state. Our results are consistent with a pressure-driven Mott-Hubbard transition.

Keywords: pressure-induced metallization; bandwidth-controlled Mott-Hubbard transition; insulator-to-metal transition; high pressure; diamond anvil cell; vanadium dioxide; VO₂; optical pump - THz probe spectroscopy
