摘要:

本文讨论了在磁场中Nambu-Jona-Lasinio模型在稠密夸克物质中形成静态双标量和赝标量密度波凝聚的可能性。在平均场近似下,得到了理论的有效势,并对其极小值进行了数值研究;构造了系统的相图。结果表明,磁场的存在有利于在低温和任意非零值的化学势的空间不均匀的冷凝配置的形成。

英文摘要:

A possibility of formation of static dual scalar and pseudoscalar density wave condensates in dense quark matter is considered for the Nambu--Jona-Lasinio model in an external magnetic field. Within a mean-field approximation, the effective potential of the theory is obtained and its minima are numerically studied; a phase diagram of the system is constructed. It is shown that the presence of a magnetic field favors the formation of spatially inhomogeneous condensate configurations at low temperatures and arbitrary non-zero values of the chemical potential.
