摘要
The influence of the Fermi surface anisotropy on the specific heat jump is studied for the p-wave superconductor with a gap function d = z^(kx ± iky) in connection with Sr2RuO4. It is shown that the normalized specific heat jump, ΔC/γTc, is reduced from its “universal” value, 1.43, in accordance with experimental findings. We show that this behavior fits well into our present understanding of the quasiparticle spectrum and the impurity effects.
