Rafael C. Nunes, Hooman Moradpour, Edésio M. Barboza, Everton M. C. Abreu, Jorge Ananias Neto

摘要:

在本文中,我们将研究非对易时空对宇宙动力学的影响。我们将黑洞熵公式推广到NC黑洞。然后,利用熵引力理论,我们将证明非对易性改变了引力场的强度。通过将这一结果应用于包含非相对论性物质和宇宙学常数的均匀各向同性宇宙,我们将表明,由时空的非对易性修改的模型比标准模型更好地拟合所获得的数据。

英文摘要:

In this paper we will investigate the effects of a noncommutative (NC) space-time on the dynamics of the universe. We will generalize the black hole entropy formula for a NC black hole. Then, using the entropic gravity formalism, we will show that the noncommutativity changes the strength of the gravitational field. By applying this result to a homogeneous and isotropic universe containing nonrelativistic matter and a cosmological constant, we will show that the model modified by the noncommutativity of the space-time is a better fit to the obtained data than the standard one.
