论文摘要
由中子恒星及其合并中可能存在的夸克物质以及运输现象在这些系统中的重要作用的动机，我们使用仪表/重力二元性进行了有史以来对不同粘度和密集夸克物质的电导率的第一个系统研究。利用V-QCD模型，我们得出了与扰动理论的预测定性分歧的结果，该结果突出了系统在弱耦合下的不同运输特性，并要求在中子星应用中使用扰动结果时要谨慎。
Motivated by the possible presence of deconfined quark matter in neutron stars and their mergers and the important role of transport phenomena in these systems, we perform the first-ever systematic study of different viscosities and conductivities of dense quark matter using the gauge/gravity duality. Utilizing the V-QCD model, we arrive at results that are in qualitative disagreement with the predictions of perturbation theory, which highlights the differing transport properties of the system at weak and strong coupling and calls for caution in the use of the perturbative results in neutron-star applications.
