We study the properties of strangelets at finite temperature $T$, employing an equivparticle model that incorporates both linear confinement and leading-order perturbative interactions with density-dependent quark masses. The shell effects are analyz

Publikováno v: Phys.Rev.D 109 (2024) 3, 034003

We investigate the properties of strangelets at finite temperature $T$, where an equivparticle model is adopted with both the linear confinement and leading-order perturbative interactions accounted for using density-dependent quark masses. The shell

Cold quark matter in a quasiparticle model: thermodynamic consistency and stellar properties

Autor: Ma, Zhi-Jun, Lu, Zhen-Yan, Xu, Jian-Feng, Peng, Guang-Xiong, Fu, Xiangyun, Wang, Junnian

Publikováno v: Physical Review D 108, 054017 (2023)

The strong coupling in the effective quark mass was usually taken as a constant in a quasiparticle model while it is, in fact, running with an energy scale. With a running coupling, however, the thermodynamic inconsistency problem appears in the conv

Interface effects of quark matter: Light-quark nuggets and compact stars

Autor: Xia, Cheng-Jun, Xu, Jian-Feng, Peng, Guang-Xiong, Xu, Ren-Xin

Publikováno v: Phys. Rev. D 106 (2022) 034016

The interface effects of quark matter play important roles in the properties of compact stars and small nuggets such as strangelets and $ud$QM nuggets. By introducing a density derivative term to the Lagrangian density and adopting Thomas-Fermi appro

Landau quantization and spin polarization of cold magnetized quark matter

Autor: Lu, Zhen-Yan, Xu, Jian-Feng, Wen, Xin-Jian, Peng, Guang-Xiong, Ruggieri, Marco

Publikováno v: Chin.Phys.C 46 (2022) 6, 064104

The magnetic field and density behaviors of various thermodynamic quantities of strange quark matter under compact star conditions are investigated in the framework of the thermodynamically self-consistent quasiparticle model. For individual species,
