概要
- 論文の詳細を見る
We show that the density of states in an anisotropic superconductor with intersecting line nodesin the gap function is proportional to 711;log(a,4(>/E) for IEI< Ag, where Ag is the maximumvalue of the gap function and a is constant, while it is proportional to E if the line nodesdo not intersect. As a result, a logarithmic correction appears in the temperature dependenceof the NIVIR relaxation rate and the specific heat, which can be observed experimentally. Bycomparing with those for the heavy fermion superconductors, we can obtain information aboutthe symmetry of the gap function.
