CONDENSED PHYSICAL CHARACTERISTICS
HATSUMI MORI LAB.
INTRODUCTION OF LABORATORY
We use nuclear magnetic resonance (NMR) as the major experimental tool to investigate various phenomena caused by strong electronic correlations and quantum fluctuations such as exotic superconductivity, unconventional order of electronic spin, orbital and charge, quantum phase transition in quantum spin and strongly correlated systems induced by high magnetic field and high pressure. Because of the magnetic and electric hyperfine interaction between nuclear magnetic and quadrupole moments and surrounding electrons, NMR is a powerful tool for microscopic investigation of the ordering and fluctuations of multiple degrees of freedom of electrons such as spin, charge and orbital. Current research topics in our lab include (1) Ground states, dynamics, and quantum phase transitions in frustrated spin systems. (2) Exotic superconductors and quantum transitions under high pressure. (3) Ordering and fluctuations of electronic multiopoles.

WHAT ARE THE INTERESTING AND PECULIAR POINTS OF ORGANIC MATERIALS IN COMPARISON WITH INORGANIC ONES?
In the high school time, I enjoyed chemical experiments. My favorite was beautiful color of transition metals and my questions were why ruby is red and sapphire is blue. My major in the University was chemistry and the research of the functional organic materials has been started. Fortunately, I discovered the new organic superconductor with the world record of the transition temperature. The discovery was beyond my expectation and the reply of nature to my question. My dream is to discover the novel functionalities in order to expand the possibilities of organic materials. Recently, we found the metallic state of the single-component of purely organic materials, even though organic materials were originally insulators. Why do not you join our group and have your enjoyable experience to find new functional materials with us?

Prof. Mori is a cheerful, kind, and energetic person who is passionate about research and education. Members at Mori Lab grow as a researcher through daily discussions with Prof. Mori and other Mori-lab members, and trial and error related to their research. Because the lab members experience both organic synthesis and physical property measurement, members can broaden their horizons and options. As a perk of being a Mori-lab member, we can gaze at beautiful single crystals of compounds we have made!
SOLID STATE PHYSICS AND CHEMISTRY
We are taking on the challenge of creating new material science by synthesizing new molecular substances and developing their functions!

The Goal of Applied Physics
The goal of Applied Physics is to develop a stage = “new material” that can manipulate undeveloped degrees of freedom, to explore unknown phenomena created from that stage and to bring out excellent functions, and to bring out its excellent functions. The purpose is to contribute to the development of human society by elucidating the mechanisms and developing application fields for these phenomena and functions.
