加速BIon中宇宙空间的产生和膨胀
Emergence and expansion of cosmic space in an accelerating BIon
摘要:
我们将Padmanabhan [arXiv:hep-th/1206.4916]机制推广到加速BIon,并表明边界表面上的自由度数量与体区域中的自由度数量之间的差异导致BIon的加速膨胀。我们还考虑了在这个玻色子上出现的宇宙的演化,得到了它的哈勃参数和能量密度。
英文摘要:
We generalize the Padmanabhan [arXiv:hep-th/1206.4916] mechanism to an accelerating BIon and show that the difference between the number of degrees of freedom on the boundary surface and the number of degrees of freedom in a bulk region causes the accelerated expansion of a BIon. We also consider the evolution of a universe which emerges on this BIon, and obtain its Hubble parameter and energy density.
