Research Abstract |
In order to understand superconducting symmetry and anomalous metallic state of unconventional superconductors, we studied the low-energy excitation of quasi-particles (QPs) by the thermal transport and specific heat measurements. As the results, we clarified the low energy QP excitation structure of iron pnictides, d-electron multi-gap superconductor, β-pyrochlore superconductor, and multicomponent superconductor. We also get new information on the quantum criticality in the anomalous metallic state of Yb compounds.
