大爆炸量子宇宙学:物质能量产生时代

The Big Bang quantum cosmology: The matter-energy production epoch

V. E. Kuzmichev, V. V. Kuzmichev

摘要:

考虑了物质-能量产生时期的均匀、各向同性封闭宇宙的精确可解量子模型。假设宇宙最初充满均匀标量场和定义了参考系的理想流体。计算了量子宇宙的定态谱和波函数。在这个模型中,宇宙中的物质能量有一个组成部分,其形式是原始标量场振荡的大质量零动量激发量子的凝聚。在给定的状态下,宇宙标度因子的平均值与凝聚态的质量之间存在线性关系。计算了从初始宇宙学奇点开始的宇宙成核率。它表明,宇宙的成核过程可以有一个指数(爆炸)的性质。宇宙的演化被描述为不同质量的凝聚态之间的非零概率跃迁。

英文摘要:

The exactly solvable quantum model of the homogeneous, isotropic and closed universe in the matter-energy production epoch is considered. It is assumed that the universe is originally filled with a uniform scalar field and a perfect fluid which defines a reference frame. The stationary state spectrum and the wave functions of the quantum universe are calculated. In this model the matter-energy in the universe has a component in the form of a condensate of massive zero-momentum excitation quanta of oscillations of primordial scalar field. The mean value of the scale factor of the universe in a given state is connected with the mass of a condensate by a linear relation. The nucleation rate of the universe from the initial cosmological singularity point is calculated. It is demonstrated that the process of nucleation of the universe can have an exponential (explosive) nature. The evolution of the universe is described as transitions with non-zero probabilities between the states of the universe with different masses of a condensate.
