摘要:

拓扑绝缘体是本体中的绝缘体,但特征在于沿着边界的手性能量传播。这种性质本质上是拓扑的,因此对无序具有鲁棒性。最初在电子材料中发现,拓扑保护的边界输运已经在许多其他物理系统中观察到。因此,人们自然会问,这一现象在更广泛的背景下是否具有相关性。我们编排了一种舞蹈,在这种舞蹈中,一群人被安排在一个正方形网格上,表现得像一个拓扑绝缘体。舞蹈的特点是通过格子边缘的舞者单向流动的运动。当人们离开舞池时,这种效果仍然存在。我们的工作将波动物理学的适用性扩展到表演艺术。

英文摘要:

Topological insulators are insulators in the bulk but feature chiral energy propagation along the boundary. This property is topological in nature and therefore robust to disorder. Originally discovered in electronic materials, topologically protected boundary transport has since been observed in many other physical systems. Thus, it is natural to ask whether this phenomenon finds relevance in a broader context. We choreograph a dance in which a group of humans, arranged on a square grid, behave as a topological insulator. The dance features unidirectional flow of movement through dancers on the lattice edge. This effect persists when people are removed from the dance floor. Our work extends the applicability of wave physics to the performance arts.
