摘要:

从经典力学到量子力学的转变在过去一直吸引着科学家,并且仍然是最先进物理学中最基本的概念挑战之一。除了量子力学的对应原理,量子-经典类比也引起了相当大的兴趣。在这项工作中,我们提出了经典的双模干涉的纳米机械双模系统,实现经典的Stückelberg干涉。在过去,Stückelberg干涉测量法只在量子力学两能级系统中进行研究。在这里,我们实验证明了一个经典的模拟的Stückelberg干涉利用两个强耦合,高品质因数纳米机械谐振器模式之间的相干能量交换。此外,我们提供了一个精确的理论解的双通道Stückelberg问题,揭示了类似的返回概率在量子力学和经典版本的问题。这一结果使经典双模系统有资格作为量子力学干涉测量的试验平台。

英文摘要:

The transition from classical to quantum mechanics has intrigued scientists in the past and remains one of the most fundamental conceptual challenges in state-of-the-art physics. Beyond the quantum mechanical correspondence principle, quantum-classical analogies have attracted considerable interest. In this work, we present classical two-mode interference for a nanomechanical two-mode system, realizing classical Stückelberg interferometry. In the past, Stückelberg interferometry has been investigated exclusively in quantum mechanical two-level systems. Here, we experimentally demonstrate a classical analog of Stückelberg interferometry taking advantage of coherent energy exchange between two-strongly coupled, high quality factor nanomechanical resonator modes. Furthermore, we provide an exact theoretical solution for the double passage Stückelberg problem which reveals the analogy of the return probabilities in the quantum mechanical and the classical version of the problem. This result qualifies classical two-mode systems at large as a testbed for quantum mechanical interferometry.
