考虑介质效应的热力学准粒子的内禀自由度
The intrinsic degree of freedom for quasiparticle in thermodynamics with medium effects
摘要:
研究了用准粒子有效质量随温度和密度变化表示的介质效应热力学。由于特殊的参数依赖性的系列困难和许多争论在参考文献中得到解决。为了解决可逆过程方程中准粒子$m^*$的不确定性,引入了一个新的独立的内禀自由度。我们证明了所有结果都是自洽的。
英文摘要:
The thermodynamics with medium effects expressed by the temperature- and density-dependent effective mass of quasiparticle is studied. Series difficulties and many wrangles in references due to the extraordinary parameter dependence are addressed. A new independent intrinsic degree of freedom of quasiparticle $m^*$ in the equation of reversible process is introduced to clear the ambiguity. We prove all results are self-consistent.
