f(R)引力中的宇宙时间箭头

Cosmological arrow of time in f(R) gravity

Bal Krishna Yadav, Murli Manohar Verma

摘要:

宇宙学的时间箭头可以通过热力学第二定律与热力学箭头联系起来。时间的不对称性也与耗散流体有关,因为托尔曼引入了粘性流体来产生循环宇宙学中的时间箭头。用标量场证明了循环宇宙学中的时间箭头,本文给出了f(R)引力中的宇宙学时间箭头。这里我们使用一个新的标量场和$f(R)$之间的关系。这个新的标量场的动力学可能会出现时间箭头。

英文摘要:

The cosmological arrow of time may be linked to the thermodynamic arrow by second law of thermodynamics. The time asymmetry is also associated with dissipative fluid as Tolman introduced a viscous fluid to generate an arrow of time in cyclic cosmology. An arrow of time in cyclic cosmology has been shown using scalar field.In this work we find out the cosmological arrow of time in f(R) gravity. Here we use the relation between a new scalar field and $f(R)$. The dynamics of this new scalar field may emerge the arrow of time.
