摘要
摘要 我们利用超统计理论框架探讨了具有非最小耦合的费米子场在一维、二维和三维的热特性。我们考虑了三种不同的分布:伽马分布、对数正态分布和 F 分布。每种分布都由特定的概率密度函数支配。为了计算分区函数,我们使用了欧拉-麦克劳林公式,特别是在超统计的低能渐近近似中。这种计算方法考虑了余项。在每种情况下,我们利用推导出的分区函数,分析了熵和比热随温度和普遍参数(表示为 \(q\))的变化而变化的情况。一般来说,我们发现增加 \(q\)的值会增强所有曲线。此外,我们注意到,熵值往往随着温度的降低而增加,随着参数 (q)的增加而降低。
Superstatistical properties of the Dirac oscillator with gamma, lognormal, and F distributions
We explore the thermal characteristics of fermionic fields with a nonminimal coupling in one, two, and three dimensions using the framework of superstatistics theory. We consider three distinct distributions: the gamma distribution, the lognormal distribution, and the F distribution. Each of these distributions is governed by a specific probability density function. To calculate the partition function, we use the Euler–Maclaurin formula, specifically in the low-energy asymptotic approximation of superstatistics. This calculation takes the remainder term into consideration. In each scenario, using the derived partition functions, we analyze the variations in entropy and specific heat with varying temperatures and the universal parameter denoted as \(q\). In general, we observe that increasing the value of \(q\) enhances all the curves. Additionally, we note that entropy values tend to increase as the temperature decreases, and tend to decrease as the parameter \(q\) increases.
