“暗物质“现象学--从埃弗雷特的量子宇宙学谈起
Phenomenology of "dark matter"- from the Everett's quantum cosmology
摘要：
人们普遍认为，埃弗雷特的（或“多世界”）解释的量子力学是唯一一个适合于量子宇宙学，因为没有环境可能存在的宇宙作为一个整体。我们在埃弗雷特解释的框架内讨论宇宙进化的（准）经典阶段，此时共存“经典不相容”的物质配置，或经典替代现实（简称“替代”）。在Everett解释的框架下，半经典引力（引力场是经典的，非引力场是量子的）比包括量子化引力场在内的理论更自然。结果表明，半经典的（至少在天体物理和宇宙学尺度上）Everett型引力导致了被称为暗物质效应的观测效应。在这种情况下，暗物质的作用不是假设物质的特殊形式（与已知物质的弱相互作用），而是由通常类型的物质发挥作用，然而，这种物质属于那些“不可见”的替代现实（埃弗雷特的世界），即在非引力场的帮助下无法感知。
英文摘要：
It is widely accepted that the Everett's (or "many-worlds") interpretation of quantum mechanics is the only one which is appropriate for quantum cosmology because no environment may exist for Universe as a whole. We discuss, in the framework of the Everett's interpretation, the (quasi-) classical stage of evolution of the Universe when there coexist "classically incompatible" configurations of matter, or classical alternative realities ("alternatives" for short). In the framework of the Everett's interpretation the semiclassical gravity (where the gravitational field is classical and the non-gravitational fields are quantum) is more natural than theories including quantizing gravitational field. It is shown that the semiclassical (at least on the astrophysical and cosmological scales) Everett-type gravity leads to the observational effect known as the effect of dark matter. Instead of assuming special forms of matter (weakly interacting with the known matter), the role of the dark matter is played in this case by the matter of the usual kind which however belongs to those alternative realities (Everett's worlds) which remain «invisible», i.e. not perceived with the help of non-gravitational fields.
