The search for new control methods over light-matter interactions is one of the engines that advances fundamental physics and applied science alike. A specific class of light-matter interaction interfaces are setups coupling photons of distinct frequencies via matter. Such devices, nontrivial in design, could be endowed with multifunctional tasking. Here we envisage for the first time an optomechanical system that bridges optical and robust, high-frequency x-ray photons, which are otherwise notoriously difficult to control. The x-ray-optical system comprises of an optomechanical cavity and a movable microlever interacting with an optical laser and with x-rays via resonant nuclear scattering. We show that optomechanically induced transparency of a broad range of photons (10 eV-100 keV) is achievable in this setup, allowing to tune nuclear x-ray absorption spectra via optomechanical control. This paves ways for metrology applications, e.g., the detection of the Thorium clock transition, and an unprecedentedly precise control of x-rays using optical photons.
寻找光与物质相互作用的新控制方法是推动基础物理学和应用科学发展的动力之一。一类特定的光与物质相互作用界面是通过物质耦合不同频率光子的装置。这类设计复杂的装置可以具备多功能任务。在此，我们首次设想了一种光机械系统，它能连接光学光子和强健的高频X射线光子，而X射线光子向来难以控制。该X射线光学系统由一个光机械腔和一个可移动的微杠杆组成，微杠杆通过共振核散射与光学激光和X射线相互作用。我们表明，在此装置中可以实现对广泛光子（10 eV - 100 keV）的光机械诱导透明，从而能够通过光机械控制来调节核X射线吸收光谱。这为计量学应用铺平了道路，例如钍钟跃迁的检测，以及利用光学光子对X射线进行前所未有的精确控制。
