Low Temperature Condensed Matter Physics

We use nuclear magnetic resonance (NMR) technique to study various quantum physical phenomena at low temperatures. In particular, we search for spin-triplet, topological superconductivity, and are interested in understanding the mechanism of superconductivity in various classes of materials including copper oxides, iron pnictides, heavy fermion compounds, non-centrocymmetric materials.
One of our current projects is on topological superconductors, whose surface states can be used for quantum computing. Here, the term “topological” means that the wave function describing superconductivity has a non-zero topological invariant, just as a donut where the number of hole is invariant against deformation.

We are currently searching for spin-triplet, topological superconductivity. We study the mechanism of superconductivity in various classes of materials including copper oxides, iron pnictides, heavy fermion compounds, non-centrocymmetric materials. In addition to NMR measurements, we also grow single crystals and perform first-principle band calculation.
