Chirality, an intrinsic handedness, is one of the most intriguing fundamental phenomena in nature. Materials composed of chiral molecules find broad applications in areas ranging from nonlinear optics and spintronics to biology and pharmaceuticals. However, chirality is usually an invariable inherent property of a given material that cannot be easily changed at will. Here, we demonstrate that ferroelectric nanodots support skyrmions the chirality of which can be controlled and switched. We devise protocols for realizing control and efficient manipulations of the different types of skyrmions. Our findings open the route for controlled chirality with potential applications in ferroelectric-based information technologies.
手性，即一种内在的旋向性，是自然界中最引人入胜的基本现象之一。由手性分子组成的材料在从非线性光学、自旋电子学到生物学和药物学等领域有着广泛的应用。然而，手性通常是给定材料的一种不变的固有属性，不易随意改变。在此，我们证明铁电纳米点支持斯格明子，其手性可以被控制和切换。我们设计了实现对不同类型斯格明子进行控制和有效操纵的方案。我们的发现为可控手性开辟了道路，在基于铁电的信息技术中具有潜在应用。
