广义和扩展的不确定原理及其对Jeans质量的影响

The generalized and extended uncertainty principles and their implications on the Jeans mass

H. Moradpour, A. H. Ziaie, S. Ghaffari, F. Feleppa

摘要:

广义和扩展的不确定原理不仅影响牛顿引力,而且影响热力学相空间的几何形状。在后者的影响下,理想气体的能量-温度关系可能发生变化。此外,似乎牛顿引力在雷尼熵形式主义的框架内被修改,这是由引力的长程性质和扩展的不确定原理所激发的。在这里,采用广义和扩展的不确定原理,而不是海森堡不确定原理,对金斯质量的后果进行了研究。在雷尼熵形式主义的工作结果也得到了解决。结果表明,广义不确定原理和Rényi熵理论都能使Jeans质量增加,而广义不确定原理能使Jeans质量减小,这意味着质量小于标准Jeans质量的云也可能经历引力坍缩过程.

英文摘要:

The generalized and extended uncertainty principles affect the Newtonian gravity and also the geometry of the thermodynamic phase space. Under the influence of the latter, the energy-temperature relation of ideal gas may change. Moreover, it seems that the Newtonian gravity is modified in the framework of the Rényi entropy formalism motivated by both the long-range nature of gravity, and the extended uncertainty principle. Here, the consequences of employing the generalized and extended uncertainty principles, instead of the Heisenberg uncertainty principle, on the Jeans mass are studied. The results of working in the Rényi entropy formalism are also addressed. It is shown that unlike the extended uncertainty principle and the Rényi entropy formalism which lead to the same increase in the Jeans mass, the generalized uncertainty principle can decrease it. The latter means that a cloud with mass smaller than the standard Jeans mass, obtained in the framework of the Newtonian gravity, may also undergo the gravitational collapse process.
