Ferroelectricity in the nematic liquid crystal under the direct current electric field
Mateusz Mrukiewicz, Paweł Perkowski, Jakub Karcz +1
We investigated the electrical properties of the liquid crystal compound, known as an RM734, exhibiting a ferroelectric nematic phase. The influence of alternating (AC) and direct…
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…
Mixing Twist-Bend and Ferroelectric nematic liquid crystals
Abinash Barthakur, Jakub Karcz, Przemyslaw Kula +1
Twist-bend (Ntb) and ferroelectric (NF) nematic liquid crystals exhibit several novel effects and new physical properties. The question of what happens in binary mixtures is intere…
Critical splay fluctuations and colossal flexoelectric effect above non-polar to polar nematic phase transition
Abinash Barthakur, Jakub Karcz, Przemyslaw Kula +1
The recent discovery of nematic liquid crystals with polar order (ferroelectric nematic) has created immense interest. Despite intensive research, several physical properties of th…
Dynamics of a sheared twist bend nematic liquid crystal
M. Praveen Kumar, Jakub Karcz, Przemyslaw Kula +1
We study the flow behaviour of a twist-bend nematic liquid crystal. It shows three distinct shear stress () responses in a certain range of temperatures and shear rat…
A ferroelectric liquid crystal confined in cylindrical nanopores: Reversible smectic layer buckling, enhanced light rotation and extremely fast electro-optically active Goldstone excitations
Mark Busch, Andriy V. Kityk, Wiktor Piecek +7
The orientational and translational order of a thermotropic ferroelectric liquid crystal (2MBOCBC) imbibed in self-organized, parallel, cylindrical pores with radii of 10, 15, or 2…
