标题： Note on a BCS analogy of Majorana neutrinos

摘要： 在本文中，我们讨论了BCS理论与中微子的跷跷板模型之间的类比关系。我们认为，这种类比揭示了马约拉纳中微子的一些基本特性。最近有一篇关于该问题的论文已发表，我们希望描述该论文的背景，并阐述我们对该问题的个人看法。本质上，从手征费米子构造传统的马约拉纳中微子过于简化了，我们认为实际上需要通过一种Bogoliubov型的正则变换，才能在跷跷板模型中从一个有效的单一Dirac费米子生成两个马约拉纳费米子。 显示英文摘要

摘要： In this note, we discuss an analogy between the BCS theory and the seesaw model of neutrinos. We believe that the analogy indicates some fundamental aspects of Majorana neutrinos. A paper on the issue has been recently presented, and we would like to describe the background of the paper together with our personal views on the problem. In essence, the conventional construction of a Majorana neutrino from a chiral fermion is too simplified, and we argue that one would actually have to go through a Bogoliubov-type canonical transformation to generate two Majorana fermions from an effective single Dirac fermion in the seesaw model.
