q变形相对论理想费米气体的热统计

Thermostatistics of a q-deformed Relativistic Ideal Fermi Gas

Xu-Yang Hou, H. Yan, Hao Guo

摘要:

本文建立了相对论性费米气体的q形变多体理论,讨论了形变参数q对系统物理性质的影响。由于反粒子激发出现在相对论范围内,为了得到一个相容的理论,必须对费米子和反费米子的形变参数的选择进行适当的处理。应用此公式,我们进一步研究了q变形的理想相对论费米气体的热统计性质。它可以表明,即使在非相互作用的情况下,该系统表现出有趣的特性,显着不同于普通的费米气体。可以解释的是,由于形变参数q使化学势移动,反粒子可能成为主导粒子。这为进一步研究q形变相对论相互作用系统奠定了坚实的基础。

英文摘要:

In this paper, we formulate a q-deformed many-body theory for the relativistic Fermi gas and discuss the effects of the deformation parameter q on physical properties of such systems. Since antiparticle excitations appear in the relativistic regime, a suitable treatment to the choice of deformation parameters for both fermions and antifermions must be carefully taken in order to get a consistent theory. By applying this formulation, we further study the thermostatistic properties of a q-deformed ideal relativistic Fermi gas. It can be shown that even in the noninteracting scenario, the system exhibits interesting characteristics which are significantly different from ordinary Fermi gases. Explicitly, antiparticles may become dominant due to the shift of chemical potential by the deformation parameter q. This may build a solid foundation for the further studies of q-deformed relativistic interacting systems.
