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…
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…
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…
Polarization Plasticity of Ferroelectric Nematics: a case of Electrostatic Frustration in Simple Planar Electrode Cells
Stefano Marni, Federico Caimi, Luca Casiraghi +5
Because of their spontaneous bulk polarization, ferroelectric nematic liquid crystals can be easily brought by surface coupling or confinement in a state in which the accumulation…
Design Principles for Fluid Molecular Ferroelectrics
Calum J Gibb, Jordan Hobbs, William C Ogle +1
Fluid molecular ferroelectrics are a new class of organic materials where ferroelectricity is found in conjunction with 3D fluidity whilst still retaining spontaneous polarization…
Modulated Anti-Ferroelectric Smectic Phases with Orthogonal and Tilted Structures
Jordan Hobbs, Calum J. Gibb, William C. Ogle +5
The discovery of the ferroelectric nematic phase has brought with it a plethora of new polar liquid crystalline phases. One in particular is the anti-ferroelectric smectic A SmA\te…
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 the recently observed spontaneous chiral symmetry breaking in polar fluids composed of achiral molecules is an unsolved problem, raising fundamental questions about h…
