摘要: The Bardeen-Cooper-Schrieffer gap equation for \ensuremath{\Delta}(k) is solved analytically a simple metal having spiral or linear spin-density wave. \ensuremath{\Delta} falls to zero at the spin-density-wave energy case, but finite (but small) value if wave linearly polarized. electronic heat capacity in superconducting state acquires low-temperature tail, far excess of BCS exponential falloff, and similar (hitherto enigmatic) behavior observed pure Pb.
