説明

The pairing symmetry for CeCoIn 5 is controversial between d x 2 - y 2 and d x y from the angle-dependent measurements of thermal conductivity and specific heat under the magnetic field, respectively. Therefore we investigate the gap structure of CeCoIn 5 , and identify it as d x 2 - y 2 symmetry. In addition, we show that two opponent factors determine the pressure dependence of T c : the momentum dependence of quasi-particle interaction, and the wave-function renormalization factor.
