再论Fischler-Susskind全息宇宙学
Fischler-Susskind holographic cosmology revisited
摘要:
当Fischler和Susskind提出一个基于粒子视界的全息处方时,他们发现空间封闭的宇宙学模型并不能验证它,因为粒子视界区域显然不可避免地会重新收缩。在这篇文章中,在简短回顾了他们的原始工作之后,我们用图形和分析的方式揭示了空间封闭的宇宙学模型可以避免这个问题,如果它们扩展得足够快的话。它还表明,全息原理是饱和的余维一膜占主导地位的宇宙。Fischler-Susskind处方用于获得与全息原理兼容的普朗克时代的每普朗克体积的最大自由度。
英文摘要:
When Fischler and Susskind proposed a holographic prescription based on the Particle Horizon, they found that spatially closed cosmological models do not verify it due to the apparently unavoidable recontraction of the Particle Horizon area. In this article, after a short review of their original work, we expose graphically and analytically that spatially closed cosmological models can avoid this problem if they expand fast enough. It has been also shown that the Holographic Principle is saturated for a codimension one brane dominated Universe. The Fischler-Susskind prescription is used to obtain the maximum number of degrees of freedom per Planck volume at the Planck era compatible with the Holographic Principle.
