论文摘要
本文旨在检查涡度对相对论量子系统热力学的影响。我们扩展了Zubarev的非平衡统计操作员方法,以解决在手性质和外部电磁场的存在下涡度引起的量子效应,并保持系统的完全协变量和量子性能。为了研究涡度的影响,这项工作集中在由无质手性费米子组成的系统上。我们恢复了文献中已知的重要量子现象,即手性磁效应,手性涡旋效应,轴向涡旋效应和手性分离效应,我们还揭示了二阶对热涡度的额外影响。这项研究还确定并介绍了在外部恒定均匀磁场的作用下由手性无质量费米组成的全局热平衡系统的热状态的精确溶液。利用这些精确的溶液和保护方程式,该研究还证明,与一阶对热涡度有关的热系数不会从外部电磁场中获得校正。相同的论点揭示了这些热系数之间的现有关系,甚至连接了与涡度有关的系数与与电磁场有关的其他关系。例如,该分析发现手性涡旋效应和手性磁效应电导率通过微分方程将一个连接到另一个。因此,这项研究提供了得出电磁场和涡度效应与相互作用之间关系的第一步。
The present thesis aimed to examine the effects of vorticity on the thermodynamics of relativistic quantum systems. We extend the Zubarev's non-equilibrium statistical operator method to address quantum effects induced by vorticity in the presence of chiral matter and external electromagnetic field and keeping full covariant and quantum properties of the system. To investigate the effects of vorticity, this work has been focused on systems consisting of massless chiral fermions. We recovered the significant quantum phenomena known in the literature, namely the chiral magnetic effect, the chiral vortical effect, the axial vortical effect and the chiral separation effect and we also revealed the presence of additional effects at second-order on thermal vorticity. This study has also identified and presented the exact solutions of thermal states for a system at global thermal equilibrium consisting of chiral massless fermions under the action of an external constant homogeneous magnetic field. Taking advantage of these exact solutions and conservation equations, the study also proved that the thermal coefficients related to first-order effects on thermal vorticity do not receive corrections from the external electromagnetic field. The same argument revealed existing relations between those thermal coefficients, even connecting coefficients related to vorticity to other related to electromagnetic field. For instance, this analysis has found that the chiral vortical effect and the chiral magnetic effect conductivities are connected one to the other by a differential equation. Therefore, this research provides the first steps into deriving the relations between the effects and the interplay of electromagnetic fields and vorticity.
