三重态凝聚中子物质的低激发模及其有效理论

The low lying modes of triplet-condensed neutron matter and their effective theory

Paulo F. Bedaque, Amy N. Nicholson

摘要:

中子凝聚成3P2超流相的密度与中子星内部的密度有关。三重态配对自发地破坏了旋转对称性,并导致了与许多输运系数和恒星冷却特性相关的无隙模式(角动量)的存在。我们推导出了低能量有效场论的主导项,包括对各种可能的3P2相有效的电弱电流的主导耦合。

英文摘要:

The condensation of neutrons into a 3P2 superfluid phase occurs at densities relevant for the interior of neutron stars. The triplet pairing breaks rotational symmetry spontaneously and leads to the existence of gapless modes (angulons) that are relevant for many transport coefficients and to the star's cooling properties. We derive the leading terms of the low energy effective field theory, including the leading coupling to electroweak currents, valid for a variety of possible 3P2 phases.
