论文摘要
粒子比其环境更热的布朗运动是标志性的平衡系统。它的研究提供了对纳米级热效应的宝贵见解。值得注意的是，它在光悬浮的颗粒中提供了很好的诊断热效应，这是一个有前途的力传感和量子物理测试的平台。因此，了解此效果中的相关参数至关重要。在这种情况下，我们使用托有NV中心的光学悬浮的纳米符号来测量颗粒的形状和材料的作用，以测量颗粒的内部温度和质量中心动力学。我们提出了一个模型，以评估纳米座的内部温度，从其动力学，适应其他颗粒。 我们还证明了其他机制会影响纳米座动力学及其在陷阱中的稳定性。最后，我们的工作通过将悬浮的纳米座符作为研究纳米热效应的绝佳工具，从而为提高光学悬浮颗粒的捕获稳定性打开了前景。
The Brownian motion of a particle hotter than its environment is an iconic out-of-equilibrium system. Its study provides valuable insights into nanoscale thermal effects. Notably, it supplies an excellent diagnosis of thermal effects in optically levitated particles, a promising platform for force sensing and quantum physics tests. Thus, understanding the relevant parameters in this effect is critical. In this context, we test the role of particles' shape and material, using optically levitated nanodiamonds hosting NV centers to measure the particles' internal temperature and center-of-mass dynamics. We present a model to assess the nanodiamond internal temperature from its dynamics, adaptable to other particles. We also demonstrate that other mechanisms affect the nanodiamond dynamics and its stability in the trap. Finally, our work, by showing levitating nanodiamonds as an excellent tool for studying nano-thermal effects, opens prospects for increasing the trapping stability of optically levitated particles.
