强磁场中的奇异夸克物质

Strange quark matter in strong magnetic fields within a confining model

Monika Sinha, Xu-Guang Huang, Armen Sedrakian

摘要:

在约束模型下,构造了强磁场中奇异夸克物质的状态方程。禁闭模型的夸克-夸克相互作用的Richardson势适当修改,以考虑强磁场。我们比较我们的结果的状态方程和磁化的物质内的MIT袋模型。这些模型之间的差异主要是由于理查森模型中夸克之间的强相互作用的动量依赖性。具体来说,我们发现,在这个模型中的奇异夸克物质的磁化有更明显的de Haas-van Alfven振荡比在MIT袋模型,这是(静态)胶子交换结构的限制势的后果。

英文摘要:

We construct an equation of state of strange quark matter in strong magnetic field within a confining model. The confinement is modeled by means of the Richardson potential for quark-quark interaction modified suitably to account for strong magnetic field. We compare our results for the equation of state and magnetization of matter to those derived within the MIT bag model. The differences between these models arise mainly due to the momentum dependence of the strong interaction between quarks in the Richardson model. Specifically, we find that the magnetization of strange quark matter in this model has much more pronounced de Haas-van Alfven oscillations than in the MIT bag model, which is the consequence of the (static) gluon-exchange structure of the confining potential.
