由真空中的悬浮粒子组成的光机系统为检验经典物理和量子物理的预言提供了极好的条件。虽然方法相似，但用于实现悬浮和捕获的不同实验设置为研究提供了独特的参数制度。在这项工作中，我们表明，由磁引力阱提供的高度各向异性和深势阱允许创建一个微米级的“分子”，由两个带相同电荷的微球在谐波电位。我们演示了探测和操纵（激发和冷却）的微球分子运动的两种不同的模式沿着最弱的陷阱axis.Optomechanical系统组成的真空中悬浮粒子提供了极好的条件来测试经典和量子物理的预测。虽然方法相似，但用于实现悬浮和捕获的不同实验设置为研究提供了独特的参数制度。在这项工作中，我们表明，由磁引力阱提供的高度各向异性和深势阱允许创建一个微米级的“分子”，由两个带相同电荷的微球在谐波电位。我们证明了检测和操纵（激发和冷却）的微球分子运动的两种不同的模式沿着最弱的陷阱轴。
Optomechanical systems composed of levitated particles in vacuum provide excellent conditions to test the predictions of both classical and quantum physics. While similar in approach, differing experimental setups used to achieve levitation and trapping provide unique parameter regimes for study. In this work, we show that the highly anisotropic and deep potential well provided by a magnetogravitational trap allows the creation of a micrometer-scale “molecule” consisting of two like-charged microspheres in a harmonic potential. We demonstrate the detection and manipulation (excitation and cooling) of two distinct modes of the microsphere molecule motion along the weakest trap axis.Optomechanical systems composed of levitated particles in vacuum provide excellent conditions to test the predictions of both classical and quantum physics.
