非粒子统计物理学

Non-particle statistical physics

A. Jakovac

摘要:

对于基元激励为复合对象的系统,给出了一致的统计物理描述。根据系统的谱函数,构造了系统的能量密度和系统总自由度的显式计算格式。通过典型的例子证明,单个准粒子的贡献在这些量中是非线性结合的。与吉布斯悖论的关系也进行了讨论。

英文摘要:

Consistent statistical physical description is given for systems where the elementary excitations are composite objects. Explicit calculational scheme is constructed for the energy density and the total number of thermodynamical degrees of freedom, based on the spectral function of the system. One demonstrates through characteristic examples that single quasiparticle contributions combine non-linearly in these quantities. Relation to the Gibbs paradox is also discussed.
