Landau theory applied to antiferroelectric ordering in ferroelectric nematic liquid crystals
Manisha Badu, Arjun Ghimire, Milon +6
The polarization and density modulation associated with antiferroelectric ordering is studied experimentally as a function of temperature in two ferroelectric nematic liquid crysta…
Helix alignment, chevrons, and edge dislocations in twist-bend ferroelectric nematics
Bijaya Basnet, Priyanka Kumari, Sathyanarayana Paladugu +6
We explore surface alignment and edge dislocations in the recently discovered twist-bend ferroelectric nematic, NTBF, in which the vector of spontaneous polarization follows an obl…
Twist, splay, and uniform domains in ferroelectric nematic liquid crystals
Maxim O. Lavrentovich, Priyanka Kumari, Oleg D. Lavrentovich
The newly-discovered ferroelectric nematic liquid crystal exhibits a variety of unique defect phenomena. The depolarization field in the material favors spontaneous spatial variati…
Conic sections in ferroelectric nematics: experiments and mathematical modeling
Priyanka Kumari, Olexandr Kurochkin, Vassili G. Nazarenko +3
Domain structure of a fluid ferroelectric nematic is dramatically different from the domain structure of solid ferroelectrics since it is not restricted by rectilinear crystallogra…
