我们在实验中演示了在由两个耦合的聚氯乙烯管段组成的声学系统中避免交叉。一段具有固定长度，而另一段具有可变长度。这些管段之间的耦合由具有可变孔大小的铝制隔膜控制。将声学系统中避免的交叉点与量子无限长方势垒的交叉点进行比较，将其分为两个区域-一个固定长度，另一个可变长度。这两个区域之间由控制两个区域之间耦合的三角洲势垒隔开。我们证明了声学系统和量子系统表现出相似的避免交叉行为。
We experimentally demonstrate an avoided crossing in an acoustic system, consisting of two coupled PVC tube sections. One section has a fixed length, while the other has a variable length. Coupling between these tube sections is controlled by an aluminum diaphragm with a variable hole size. The avoided crossings in the acoustic system are compared to those of a quantum infinite square well split into two regions—one of fixed length and another of variable length. The two regions are separated by a delta potential well that controls the coupling between the two regions. We demonstrate that the acoustic and quantum systems exhibit similar avoided crossing behaviors.
