The universal laws of complex systems close to phase transitions can often be expressed by scaling relations. We measured quantum phase transition metal-insulator-transition (MIT) in yttrium hydride. Yttrium hydride YH/sub x/ shows a remarkable transitions of its electronic and optical properties upon change of hydrogen concentration. Also we demonstrate that terahertz spectroscopy is a perfect tool to explore the frequency-temperature scaling in condensed matter.
