Exploring and Controlling Low Temperature Properties of Materials

In this laboratory, we study the quantum phenomena occurring at low temperatures in various superconductors and highly correlated electron systems. In addition to understanding the fundamental properties of these materials, we focus on controlling them in the form of thin fi lms and devices, which leads to fi nding novel physical phenomena. The current research subjects are the electric-fi eld-induced superconductivity, two dimensional superconductivity with atomic-layer structures and exotic superconductivity in magnetic fi elds realized in electric double layer transistor confi gurations, and the ground state of rare earth compounds.

This laboratory also contributes to the support works at Center for Low Temperature Science, where we supply liquid helium for various research fi elds and teach the low-temperature experimental techniques. Various experimental facilities for low temperature researches are open to the scientists of Tohoku University and cooperative researches are now in progress.
