作为宇宙外部量子隧穿系数的宇宙学常数

Cosmological Constant as the Coefficient of Quantum Tunneling in the Universe Exterior

Vladan Pankovic, Miodrag krmar, Sima Ciganovic

摘要:

在这项工作中,我们提出了一个简单的模型的宇宙学常数作为量子隧穿系数的真空涨落(波长大于普朗克长度)在微小的,边界球壳的宇宙(厚度相当于普朗克长度和半径相当于标度因子)。粗略地说,给定的涨落可以通过量子隧穿(即用势垒散射,势垒的能量等于普朗克能量,宽度与大约300普朗克长度成比例)离开宇宙并到达其外部,即多宇宙(在林德混沌暴胀理论的意义上,宇宙可以被认为是一个因果-而其外部可以被认为是与宇宙没有腔-腔联系的空间域)。这与通常的量子力学和量子场论以及WMAP观测数据(特别是微调条件)完全一致。

英文摘要:

In this work we suggest a simple model of the cosmological constant as the coefficient of the quantum tunneling of vacuum fluctuations (with wave length larger than Planck length) at tiny, boundary spherical shell of the universe (with thickness equivalent to Planck length and radius equivalent to scale factor). Roughly speaking, given fluctuations can, by quantum tunneling (i.e. scattering with a potential barrier with highness equivalent to Planck energy and width proportional to, approximately, three hundred Planck length) leave universe and arrive in its exterior, i.e. multi-universe (in sense of Linde chaotic inflation theory universe can be considered as a causally-luminally connected space domain while its exterior can be considered as a space domain without causal-luminal connections with universe). It is in full agreement with usual quantum mechanics and quantum field theory as well as WMAP observational data (especially fine tuning condition).
