Mikhail Ivanovich Eremets (born January 3, 1949) is an experimentalist in high pressure physics, chemistry and materials science. He is particularly known for his research on superconductivity, having discovered the highest critical temperature of 250 K (-23°C) for superconductivity in lanthanum hydride under high pressures. Part of his research contains exotic manifestations of materials such as conductive hydrogen, polymeric nitrogen and transparent sodium.
