Competing ferroelectric and smectic order: modulated structures through molecular design
Grant J. Strachan, Ewa Górecka, Jadwiga SzydÅowska +1
We demonstrate that the balance between polar and positional order can be systematically tuned through molecular engineering, providing direct control over the emergence of polar a…
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…
The balance between paraelectricity and ferroelectricity in non-chiral smectic homologs
Dorota WÄgÅowska, MichaÅ CzerwiÅski, Robert Dzienisiewicz +4
Non-chiral liquid crystals (LCs) exhibiting ferroelectricity, distinguished by their dynamic responsiveness to external stimuli and high spontaneous polarization, provide renewed i…
Spontaneous polar and chiral symmetry breaking in ordered fluids -- heliconical ferroelectric nematic phases
Jakub Karcz, Jakub Herman, Natan RychÅowicz +5
It is known that the chiral interaction described by Dzyaloshinskii-Moriya (DMI) term lead to the plethora of topological structures of magnetic spins, such as helical or skyrmion…
Nematic and smectic phases with proper ferroelectric order
Grant J. Strachan, Ewa Górecka, Jadwiga SzydÅowska +2
A material showing a sequence of three ferroelectric liquid crystalline phases below the paraelectric nematic phase has been synthesized and studied. The polar order of molecules a…
