摘要：

暗物质可能以不对称暗星的形式表现出来。在本文中，我们考虑使用原子钟探测这种不对称玻色子暗物质星的可能性。如果暗区通过希格斯玻色子或光子入口与标准模型区相连，那么处于玻色-爱因斯坦凝聚体状态的玻色子星的内部就可以改变控制原子钟装置计时的物理常数的值。通过地球的稀释不对称暗物质玻色子星可以引起频率偏移，可以在分离的地球原子钟中观察到。这就给了我们机会去探测一类暗物质候选者，而这些候选者目前还不能用任何不同的传统方法来探测。

英文摘要：

Dark Matter could potentially manifest itself in the form of asymmetric dark stars. In this paper we entertain the possibility of probing such asymmetric bosonic dark matter stars by the use of atomic clocks. If the dark sector connects to the standard model sector via a Higgs or photon portal, the interior of boson stars that are in a Bose-Einstein condensate state can change the values of physical constants that control the timing of atomic clock devices. Dilute asymmetric dark matter boson stars passing through the Earth can induce frequency shifts that can be observed in separated Earth based atomic clocks. This gives the opportunity to probe a class of dark matter candidates that for the moment cannot be detected with any different conventional method.
