Polar and apolar light-induced alignment of ferroelectric nematic at photosensitive polymer substrate
Ruslan Kravchuk, Oleksandr Kurochkin, Vassili G. Nazarenko +4
Surface alignment of a recently discovered ferroelectric nematic liquid crystal (NF) is usually achieved by buffed polymer films, which produce a unidirectional polar alignment of…
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…
Director-layer dynamics in the antiferroelectric smectic-ZA phase of a ferroelectric nematic liquid crystal
Arjun Ghimire, Bijaya Basnet, Hao Wang +7
A dynamic light scattering study of director-layer fluctuations in the antiferroelectric smectic-ZA phase of the ferroelectric nematic liquid crystal DIO is reported. The dynamics…
Periodic splay Fréedericksz transitions in a ferroelectric nematic
Bijaya Basnet, Sathyanarayana Paladugu, Oleksandr Kurochkin +5
Electric field-induced splay of molecular orientation, called the Fréedericksz transition, is a fundamental electro-optic phenomenon in nonpolar nematic liquid crystals. In a ferro…
Confinement and magnetic field effect on chiral ferroelectric nematic in Grandjean-Cano wedge cells
Kamal Thapa, Olena S. Iadlovska, Bijaya Basnet +4
We explore the structure and magnetic field response of edge dislocations in Grandjean-Cano wedge cells filled with chiral mixtures of the ferroelectric nematic mesogen DIO. Upon c…
Chiral ground states of ferroelectric liquid crystals
Priyanka Kumari, Bijaya Basnet, Maxim O. Lavrentovich +1
Ferroelectric nematic liquid crystals are formed by achiral molecules with large dipole moments. Its three-dimensional orientational order is universally described as unidirectiona…
Ferroelectric nematic liquids with conics
Priyanka Kumari, Bijaya Basnet, Hao Wang +1
Spontaneous electric polarization of solid ferroelectrics follows aligning directions of crystallographic axes. Domains of differently oriented polarization are separated by domain…
Soliton walls paired by polar surface interactions in a ferroelectric nematic liquid crystal
Bijaya Basnet, Mojtaba Rajabi, Hao Wang +5
Surface interactions are responsible for many properties of condensed matter, ranging from crystal faceting to the kinetics of phase transitions. Usually, these interactions are po…
