Fluid ferroelectric nematic fibres — •Alexander Jarosik and Alexey Eremin — Otto-von-Guericke Universität, Magdeburg, Germany

Nematics with a broken polar symmetry is one of the fascinating recent discoveries in soft matter. High spontaneous polarisation and the fluidity of the ferroelectric nematic NF phase make such materials attractive for future applications and interesting for fundamental research. We report the first example of metastable fluid fibres formed in the ferroelectric phase and characterise their polar and nonlinear optical properties. We discuss the filament stability in the frame of the polarisation-splay model of the ferroelectric nematic phase.
