Superconductivity and superfluidity in dense quark and nuclear matter

在这个博士项目中，我们从理论上研究了致密的核物质和夸克物质，并探索了它在中子星物理中的应用。特别强调了稠密物质的超导和超流体性质。例如，作为该项目的第一部分，研究了色味锁定夸克物质中的磁通管。其目的是通过一个更现实的设置来扩展之前的研究，其中包括奇怪的夸克质量。这将在Ginzburg-Landau方法的框架内完成，并将涉及通量管轮廓和域壁的数值计算。然后，这些技术也可以应用于致密的核物质，可能包括中子和质子流体之间的夹带效应。

In this PhD project, dense nuclear and quark matter is investigated theoretically and applications to the physics of neutron stars are explored. Particular emphasis is put on superconducting and superfluid properties of dense matter. For instance, as a first part of the project, magnetic flux tubes in color-flavor locked quark matter are investigated. The goal is to extend previous studies by a more realistic setup that includes the strange quark mass. This will be done in the framework of a Ginzburg-Landau approach and will involve the numerical calculation of flux tube profiles and domain walls. These techniques can then also be applied to dense nuclear matter, possibly including effects of entrainment between the neutron and proton fluids.
