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

摘要： 在本工作中，我们提出一个简单的宇宙常数模型，作为真空涨落（波长大于普朗克长度）在宇宙微小的、边界球壳（厚度等同于普朗克长度，半径等同于标度因子）处的量子隧穿系数。 粗略地说，给定的涨落可以通过量子隧穿（即与势垒散射，势垒高度等同于普朗克能量，宽度与大约三百个普朗克长度成正比）离开宇宙并到达其外部，即多宇宙（在林德混沌暴胀理论中，宇宙可被视为一个因果光速连接的空间区域，而其外部则可视为与宇宙无因果光速联系的空间区域）。 这与通常的量子力学和量子场论以及WMAP观测数据（特别是精细调节条件）完全一致。 显示英文摘要

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).
