纳米尺度下的赝磁场
Pseudomagnetic fields for sound at the nanoscale
摘要：
在产生声波的手性传输方面有越来越多的努力。然而，到目前为止，大多数方法都局限于宏观尺度。在这里，我们提出了一种新的方法，适用于纳米尺度，这是基于伪磁场。这些场类似于应变石墨烯中电子的赝磁场的声音。在我们的建议中，它们是通过简单的几何修改现有的和实验证明的声子晶体设计，雪花晶体。该平台是鲁棒的，可扩展的，并且非常适合于各种激励和读出机制，其中包括光学机械方法。
英文摘要：
There is a growing effort in creating chiral transport of sound waves. However, most approaches so far are confined to the macroscopic scale. Here, we propose a new approach suitable to the nanoscale which is based on pseudomagnetic fields. These fields are the analogon for sound of the pseudomagnetic field for electrons in strained graphene. In our proposal, they are created by simple geometrical modifications of an existing and experimentally proven phononic crystal design, the snowflake crystal. This platform is robust, scalable, and well-suited for a variety of excitation and readout mechanisms, among them optomechanical approaches.
