摘要

在这篇纪念A.F. Andreev院士的文章中，我们考虑了超低温下超流体（^{3}\）He-B的实验结果。这些实验直接证明了无间隙马约拉纳准粒子的存在，它们作为安德烈耶夫束缚态出现在超（^{3}\）He-B的边界（Silaev和Volovik在JETP 119:1042，2014）。对超流体（^3\）He-B热容量的精确测量表明，在0.12 mK的温度下，马约拉纳费米子在我们的实验条件下可以占到（50%\）的（^3\）He-B热容量。

Majorana Fermions as Andreev Bound States in Superfluid $^3$He-B

In this article in memory of academician A.F. Andreev, we consider the results of experiments in superfluid $^{3}$He-B at ultralow temperatures. These experiments directly demonstrate the existence of gapless Majorana quasiparticles, which appear as Andreev bound states at the boundary of superfluid $^3$He-B (Silaev and Volovik in JETP 119:1042, 2014). Precision measurements of the heat capacity of superfluid $^3$He-B showed that at a temperature of 0.12 mK, Majorana fermions can account for up to $50\%$ of the heat capacity of $^3$He-B in our experimental conditions.
