采用非局域SU(2) Polyakov-Nambu-Jona-Lasinio模型，研究虚化学势下磁化夸克物质的相结构，揭示磁场对退禁闭、Roberge-Weiss相变及手征区域逆磁催化的影响，与格点QCD结果定性吻合。
AI 中文摘要
我们采用非局域SU(2) Polyakov-Nambu-Jona-Lasinio模型研究磁化夸克物质的相结构，重点关注均匀外磁场存在时温度与虚化学势的相互作用，强调退禁闭相变和Roberge-Weiss相变。我们分析相关临界温度对外场的依赖关系，探究相结构对不同Polyakov圈有效势的敏感性。结果与格点QCD结果定性一致，在手征区域重现逆磁催化效应，且Roberge-Weiss相变温度随磁场增强呈下降趋势。
英文摘要
We investigate the phase structure of magnetized quark matter within a nonlocal SU(2) Polyakov-Nambu-Jona-Lasinio model. Our work focuses on the interplay between temperature and imaginary chemical potential in the presence of an external uniform magnetic field, with emphasis on the deconfinement and Roberge-Weiss transitions. We analyze the dependence of the relevant critical temperatures on the external field, and we explore the sensitivity of the phase structure to different Polyakov loop effective potentials. Our results show qualitative agreement with lattice QCD findings, reproducing inverse magnetic catalysis in the chiral sector and a decreasing behavior of the Roberge-Weiss transition temperature with increasing magnetic field.
