摘要:

本文导出了简并夸克物质中中微子平均自由程和发射率的表达式,这些表达式在非费米液体修正的情况下达到次领先阶。对吸收和散射过程进行了计算。随后,这些非线性光学修正的作用上的冷却的中子星已被证明。冷却曲线显示适度增强相比,领先的顺序(LO)的非费米液体的结果。尽管与自由费米气体相比,MFP和发射率的总体校正更大,但冷却行为没有显著改变。

英文摘要:

In this work we derive the expressions of the neutrino mean free path(MFP) and emissivity with non Fermi liquid corrections up to next to leading order(NLO) in degenerate quark matter. The calculation has been performed both for the absorption and scattering processes. Subsequently the role of these NLO corrections on the cooling of the neutron star has been demonstrated. The cooling curve shows moderate enhancement compared to the leading order(LO) non-Fermi liquid result. Although the overall correction to the MFP and emissivity are larger compared to the free Fermi gas, the cooling behavior does not alter significantly.
