我们对弯曲材料表面附近的反氢原子 ($ ar{H}$) 的运动进行了理论研究。我们预测存在 $ ar{H}$ 原子长寿命准静止态，由于卡西米尔-波尔德/范德华势的量子反射，该态位于表面附近。这种状态是声学、光学和中子物理学中已知的回音壁模式的原子波模拟。我们认为 $ ar{H}$ 原子的回音壁态可以被视为最近预测的 $ ar{H}$ 引力态的完全模拟，其中离心势起着线性引力势的作用。
We present a theoretical study of the motion of an antihydrogen atom ($ar{H}$) near a curved material surface. We predict existence of $ar{H}$ atom long-living quasistationary states, localized near the surface due to quantum reflection from the Casimir-Polder/van der Waals potential. Such states are an atom-wave analog of the whispering gallery modes, known in acoustics, optics and neutron physics. We argue that the whispering gallery states of $ar{H}$ atoms could be regarded as a full analog of recently predicted gravitational states of $ar{H}$, where the centrifugal potential plays a role of the linear gravitational potential.
