热奇异强子星物质中$Λ$超子的超流性

Superfluidity of $Λ$ hyperons in warm strange hadronic star matter

Ren-li Xu, Chen Wu, Zhongzhou Ren

摘要:

本文研究了$β$稳定奇异强子物质中$Λ$超子的$^1S_0$超流性。在相对论平均场理论下,研究了有限重子密度和温度下强子物质的物态方程。系统地研究了引入的等标矢量交叉相互作用项对$Λ$超流性的影响。此外,还讨论了温度对强子物质中$Λ$超子超流性的影响。发现$Λ$对隙的密度区域和大小依赖于交叉相互作用项。得到了$Λ$超流体的最大临界温度约为$10^9$ K。

英文摘要:

In this work we evaluate the $^1S_0$ superfluidity of $Λ$ hyperons in $β$-stable strange hadronic matter. We investigate the equation of state (EOS) of hadronic matter at finite values of baryon density and temperature in the relativistic mean field (RMF) theory. Effects of the introduced isoscalar-isovector cross-interaction term on the $Λ$ superfluidity are investigated systematically. In addition, the temperature effects on the superfluidity of $Λ$ hyperons in hadronic matter are discussed. It is found that the density region and the magnitude of the $Λ$ pairing gap are dependent on the cross-interaction term. The obtained maximal critical temperature of $Λ$ superfluid is around $10^9$ K.
