中子物质三重态相的有质量和无质量模

Massive and massless modes of the triplet phase of neutron matter

Paulo F. Bedaque, Amy N. Nicholson, Srimoyee Sen

摘要:

密度为核饱和密度量级的中子物质被认为在3P2通道中具有成对的中子。我们研究了这一阶段的低躺模式,并找到两个无质量模式(角动量),导致自发破缺的旋转对称性以及其他三个,带隙模式。我们计算它们在任意温度下的质量。

英文摘要:

Neutron matter at densities of the order of the nuclear saturation density is believed to have neutrons paired in the 3P2 channel. We study the low lying modes of this phase and find two massless modes (angulons), resulting from the spontaneous breaking of rotational symmetry as well as three other, gapped modes. We compute their masses at arbitrary temperatures.
