Mechanisms of QCD in an external magnetic field

极端条件下强相互作用物质的新相是各种重离子碰撞实验的主题，例如在欧洲核子研究中心。底层夸克和胶子的动力学由量子色动力学（QCD）控制，在这些区域中必须进行非微扰处理。在格点QCD框架下的数值模拟提供了关于高温和强磁场存在下的跃迁信息，这是近年来引起人们极大兴趣的。该项目旨在使用分析方法和对格点构型（具有物理夸克质量）的评估相结合，详细分析具有外部磁场的QCD机制。它集中在夸克本征模，Polyakov环和拓扑密度的行为，鉴于过渡和手征磁效应，以及更好地理解QCD作为一个强耦合系统的理论。

New phases of strongly interacting matter under extreme conditions are the subject of various heavy ion collision experiments, for instance at CERN. The dynamics of the underlying quarks and gluons is governed by Quantum Chromodynamics (QCD), which has to be treated nonperturbatively in these regimes. Numerical simulations in the framework of lattice QCD provide information about the transition at high temperatures and in the presence of strong magnetic fields, which have become of great interest in recent years.The project aims at analyzing the mechanisms of QCD with external magnetic fields in detail, using a combination of analytic approaches and evaluations on lattice configurations (with physical quark masses). It focusses on the behavior of the quark eigenmodes, Polyakov loops and the topological density, in view of the transition and the Chiral magnetic effect as well as for a better theoretical understanding of QCD as a strongly coupled system.
