  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.
