有限化学势非广延热力学与质子中子星

Nonextensive thermodynamics with finite chemical potentials and protoneutron stars

Eugenio Megias, Debora P. Menezes, Airton Deppman

摘要:

本文导出了具有有限化学势的玻色子和/或费米子组成的理想量子气体的非广延热力学。我们发现协议与以前的工作时,$μ\le m$,并纠正了一些不一致的费米子时,$μ> m$。这种形式主义,然后使用强子共振气体方法的基础上研究强子系统的物理性质。我们应用这个结果研究了几种条件下的质子中子星稳定性。

英文摘要:

We derive the nonextensive thermodynamics of an ideal quantum gas composed by bosons and/or fermions with finite chemical potentials. We find agreement with previous works when $μ\le m$, and some inconsistencies are corrected for fermions when $μ> m$. This formalism is then used to study the thermodynamical properties of hadronic systems based on a Hadron Resonance Gas approach. We apply this result to study the protoneutron star stability under several conditions.
