物质暗区的量子几何动力学描述--宇宙的能量含量

Quantum geometrodynamical description of the dark sector of the matter-energy content of the universe

V. E. Kuzmichev, V. V. Kuzmichev

摘要:

在严格可解的Robertson-Walker度规动力学量子模型中研究了宇宙的演化。研究表明,描述宇宙膨胀或收缩的运动方程,对于任意质量的粒子,可以用总能量为零的守恒定律的形式来表示。模拟粒子在由空间曲率、物质、经典和量子引力源的压力产生的内力的作用下在势阱中运动。在宇宙演化的某个特定阶段,这种力可以对宇宙做正功,类似于暗能量的排斥力的功,也可以做负功,类似于暗物质的吸引力的功。被认为是真实的和复杂的状态向量的情况下,描述充满尘埃和辐射的宇宙的几何性质。它表明,量子模型的预测并不矛盾的观测数据,我们的宇宙加速膨胀。

英文摘要:

The evolution of the universe is studied in exactly solvable dynamical quantum model with the Robertson-Walker metric. It is shown that the equation of motion which describes the expansion or contraction of the universe can be represented in the form of the law of conservation of zero total energy for a particle with arbitrary mass being an analogue of the universe. The analogue particle moves in the potential well under the action of the internal force produced by the curvature of space, matter, and pressures of classical and quantum gravitational sources. At a definite stage of the evolution of the universe, this force can perform the positive work on the universe, which is similar to the work of the repulsive forces of dark energy, or it does the negative work analogous to the work of the attractive forces of dark matter. The cases of real and complex state vectors which describe the geometrical properties of the universe filled with dust and radiation are considered. It is shown that predictions of the quantum model do not contradict the observational data about the accelerating expansion of our universe.
