Simulations of twist-bend nematic droplets with radial anchoring reveal a large catalogue of metastable textures, including twisted hedgehogs, Mexican-hat and pinwheel layers, defect strings, and a narrow parameter window of stable Hopfions.
In a droplet of radius R we choose q0 = 2N π/R for various values of N —care should be taken when com- paring with other studies, for example Refs

Geometric Frustration in Twist-Bend Nematic Droplets
Simulations of twist-bend nematic droplets with radial anchoring reveal a large catalogue of metastable textures, including twisted hedgehogs, Mexican-hat and pinwheel layers, defect strings, and a narrow parameter window of stable Hopfions.
