Mirror vs. inversion symmetry breaking in mesogenic dimers: NTB vs. NF phase
Małgorzata Bakiera, Jakub Karcz, Damian Pociecha +4
The recently discovered twist-bend nematic NTB and ferroelectric nematic NF phases are distinct examples of spontaneous symmetry breaking in liquid crystals. Here, we report the oc…
Competing ferroelectric and smectic order: modulated structures through molecular design
Grant J. Strachan, Ewa Górecka, Jadwiga Szydłowska +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…
Polar order in a fluid like ferroelectric with a tilted lamellar structure -- observation of a polar smectic C (SmC) phase
Jordan Hobbs, Calum J. Gibb, Damian Pociecha +3
The discovery of fluid states of matter with spontaneous bulk polar order is appreciated as a major discovery in the fields of soft matter and liquid crystals. Typically, this mani…
Nematic and smectic phases with proper ferroelectric order
Grant J. Strachan, Ewa Górecka, Jadwiga Szydłowska +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…
Spontaneous polar and chiral symmetry breaking in ordered fluids -- heliconical ferroelectric nematic phases
Jakub Karcz, Jakub Herman, Natan Rychłowicz +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…
