特拉维夫大学的研究人员发布了一个关于超导物理学的精彩 YouTube 视频,特别是关于被称为“量子俘获”和“量子悬浮”的现象。

在视频中,我们看到一个陶瓷圆盘悬浮在磁性表面之上。陶瓷圆盘被冷却到零下 185 摄氏度以下,在那里它变成超导体,通过平衡磁场中的扰动,圆盘的方向可以锁定在两个轴上的位置,使其能够以一定角度在表面上滑行。

不难想象,使用这样的技术来开发新一代高速列车;用于传统轴承或衬套可能不足以胜任的制造应用;在光伏系统中跟踪太阳;或作为化工厂中的一系列传感器。当然,将陶瓷冷却到零下 185 摄氏度并非没有成本,并且需要能量。

对于我们这些在 80 年代长大的人来说,拥有交通运输领域的终极设备的梦想——马蒂·麦克弗莱的悬浮滑板或卢克·天行者的陆地飞车——可能离现实更近了一步。或者至少是更高效的制造工艺。
