Shibauchi&Hashimoto Laboratory is a new research group in Kashiwa campus of the University of Tokyo founded in 2014. Our research interests focus on various novel "Quantum Phases of Matter", including unconventional superconductivity, hidden order phase, and quantum spin liquid. We are also studying the anomalous properties associated with the quantum critical point, which is a zero-temperature boundary between two different phases.

Professor Taka Shibauchi has been working in Department of Physics, Kyoto University for more than 8 years and he just moved to Department of Advanced Materials Science, Graduate School of Frontier Sciences, Univetsity of Tokyo. He is also responsible for teaching the undergraduate corses in Department of Applied Physics, University of Tokyo. For more details, please visit here.

We are studying several "Quantum Phases" in condensed matter, which appear at low temperatures owing to the strong electron-electron interactions and quantum effects. Our goal is to clarify the nature of these phases and to pursue the universality as well as diversity in physical sciences. The current projects include the following research themes:

Unconventional superconductivity

We are trying to elucidate the mechanism of superconductivity which is not explained by BCS theory.

Quantum critical phenomena

We are trying to understand the quantum critical phenomena which often appear when one suppresses the ordered phase by control parameters such as carrier concentration, pressure, and magnetic field.

Electron nematic phase

We are studying the electron nematic phase which spontaneously breaks the rotational symmetry of underlying crystal lattices.

Our approach to these phenomena is to perform high-precision measurements of low-temperature physical quantities by using state-of-the-art techniques. For example, we are able to measure magnetic penetration depth, which is one of the most fundamental quantities of a superconductor, down to below 100 mK with a precision better than 0.1 angstrom.

If you are interested in joining us, please contact Prof. Shibauchi. Currently, we have no available postdoc positions, but you may apply for JSPS Fellowship programs. Please note that these fellowships are competitive so you need to have a good record of achievements.
