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…

Interplay of polar order and positional order in liquid crystals -- observation of re-entrant ferroelectric nematic phase
Grant Strachan, Shona Ramsay, Marijus Juodka +6
We show that development of polar order may spontaneously destroy the lamellar structure of a liquid crystal. This results in an unusual sequence of phases with the ferroelectric n…

Twist Grain Boundary phases in proper ferroelectric liquid crystals realm
Damian Pociecha, Jadwiga Szydlowska, NataÅ¡a VaupotiÄ +7
The twist-grain-boundary (TGB) phases, characterized by a periodic, helical arrangement of blocks made of polar smectic phases, SmAF and SmCF, have been discovered. They have been…
