论文摘要
我们考虑了艾科尼尔近似中星系内的真空极化，发现存在两种可能的极化类型。第一种类型由状态等式$ p =ρ/3 $描述，类似于辐射。如果存在一个紧凑的天体物理物体，则使用共形较小的度量度量可以为该真空'''物质'构建非词性溶液。结果，出现``暗''银河系光环，该光环增加了测试粒子的旋转速度，这是距银河中心距离的函数。第二种真空极化具有更复杂的状态方程。作为静态物理作用，它会产生重力常数的重新归一化，因此不会引起静态光环。然而，第二种的非平稳极化是由于在某些假设的时间依赖性过程中随时间增加了银河核质量（或减少）的指数增加（或减少），从而产生的引力电势看起来像暗物质光环。
We considered a vacuum polarization inside a galaxy in the eikonal approximation and found that two possible types of polarization exist. The first type is described by the equation of state $p=ρ/3$, similar to radiation. Using the conformally-unimodular metric allows constructing a nonsingular solution for this vacuum ``substance'', if a compact astrophysical object exists in the galaxy's center. As a result, a ``dark'' galactical halo appears that increases the rotation velocity of a test particle as a function of the distance from a galactic center. The second type of vacuum polarization has a more complicated equation of state. As a static physical effect, it produces renormalization of the gravitational constant, thus, causing no static halo. However, a nonstationary polarization of the second type, resulting from an exponential increase (or decrease) of the galactic nuclei mass with time in some hypothetical time-dependent process, produces a gravitational potential looking like a dark matter halo.
