Abstract

We examine the behavior of highly magnetized two-light-flavor quark matter within the context of a nonlocal NJL-type model. This analysis assumes the chiral limit $(m_{c} = 0)$ and incorporates the interaction between fermions and the Polyakov loop. Our calculations utilize a covariant Gaussian form factor. We present phase diagrams on the $T - μ$ plane, illustrating different magnetic field strengths. Additionally, we examine the critical endpoint's placement and the de Haas-Van Alphen transitions within the chiral restored phase, observing their temperature-dependent characteristics.

手性极限中的高磁化夸克物质

我们在非局域 NJL 型模型的背景下研究了高度磁化的双光味夸克物质的行为。这一分析假设了手性极限 (mc=0)$$ \left({m}_c=0\right) $$，并纳入了费米子与波里雅科夫环之间的相互作用。我们的计算采用了协变高斯形式因子。我们展示了 T-μ$$ T-\mu $$ 平面上的相图，说明了不同的磁场强度。此外，我们还研究了临界端点的位置和手性恢复相中的 de Haas-Van Alphen 转变，观察了它们随温度变化的特性。

期刊介绍： Astronomische Nachrichten, founded in 1821 by H. C. Schumacher, is the oldest astronomical journal worldwide still being published. Famous astronomical discoveries and important papers on astronomy and astrophysics published in more than 300 volumes of the journal give an outstanding representation of the progress of astronomical research over the last 180 years. Today, Astronomical Notes/ Astronomische Nachrichten publishes articles in the field of observational and theoretical astrophysics and related topics in solar-system and solar physics. Additional, papers on astronomical instrumentation ground-based and space-based as well as papers about numerical astrophysical techniques and supercomputer modelling are covered. Papers can be completed by short video sequences in the electronic version. Astronomical Notes/ Astronomische Nachrichten also publishes special issues of meeting proceedings.
