Broken Inversion Symmetry via a Magic Methyl Effect
Calum J Gibb, Jordan Hobbs, Caitlin O Brien +4
Polar liquid crystals - fluid phases in which molecular dipoles organise into ferro- or antiferroelectric states - present a highly constrained molecular design space, where small…
Direct visualization of local electric fields in a layer of a ferroelectric nematic liquid
Anej Sterle, Natan Osterman, Calum J. Gibb +4
Ferroelectric nematic liquids exhibit complex ferroelectric domains shaped by competing elastic and electrostatic interactions. Using fluorescence and polarizing optical microscopy…
Molecular Hyperpolarisability as a Screening Descriptor for Second-Order Nonlinear Optics in Ferroelectric Nematic Liquid Crystals
Charles Parton-Barr, Nerea Sebastian, Richard Mandle
The paper evaluates density‑functional theory calculations of molecular hyperpolarizability as a screening tool for identifying ferroelectric nematic liquid crystals with strong se…
Exotic topological defects and director fields in free-floating spherical ferroelectric nematic liquid crystal shells
Churchill B. Agoni, Ema Pilih, Luka Cmok +5
Ferroelectric nematic (NF) liquid crystals exhibit polar symmetry and large polarization, giving rise to phenomena absent in conventional apolar nematics. We investigate NF liquid…
Flexoelectricity-driven softening of bend elasticity leads to spontaneous chiral symmetry breaking in a polar fluid
Aitor Erkoreka, Josu Martinez-Perdiguero, Luka Cmok +6
The origin of recently observed spontaneous chiral symmetry breaking in polar fluids is an unsolved problem, and poses fundamental questions as to how heliconical structures emerge…
Elasticity-Driven Periodic Polarization Patterns in Confined Chiral Ferroelectric Nematic Fluid
Anej Sterle, Peter Medle-Rupnik, Luka Cmok +9
Ferroelectric nematic phases are a new class of polar fluids in which spontaneous polarization is directly coupled to the orientational order, providing unique opportunities for cr…
