Unraveling The Mystery of Quantum Materials

We conduct experimental research on a variety of topics in quantum condensed matter physics using NMR (Nuclear Magnetic Resonance) as the primary experimental probe.  NMR is a technique invented by physicists, but it is used for MRI in hospitals as well.  Nuclear spins interact with electrons in their vicinity via hyperfine interactions.  By observing how nuclear spins respond to perturbations caused by radio frequency pulses we apply, we figure out what electrons are doing.  In other words, we use the nuclear spins as a “spy” of electrons in quantum solids. 

We conduct NMR experiments using our own NMR spectrometers and superconducting magnets in our laboratory.  Our recent research topics include: quantum spin liquids on the Kagome-lattice Heisenberg antiferromagnet, quantum spin liquids on the Kitaev honeycomb lattice, quantum criticality of the transverse field Ising chain, and strongly correlated electros in copper-oxide high temperature superconductors. 

We are always looking for enthusiastic students, who want to participate in our research.  If you wish to know more details, please visit our homepage or contact me.

We are a research group specialized in experimental investigation of quantum materials.  Our primary experimental probe is Nuclear Magnetic Resonance (NMR) conducted at cryogenic temperatures near absolute zero.  We investigate a variety of materials, such as the “spin liquid” on the kagome Heinsenberg model, iron-based high temperature superconductors, etc.  We try to focus our attention on the most important problems, and aim for publishing a small number of high-impact papers.  We are always looking for enthusiastic students who want to participate in the cutting edge research in our lab.
