Tunable macroscopic defect patterns induced by a low-frequency AC electric field in ferroelectric nematic liquid crystals
Natalia Podoliak, Lubor Lejcek, Martin Cigl +1
Regulation of topological structures and pattern formation is attracting wide interest in the field of condensed matter. Liquid crystals (LCs) represent soft matter with a remarkab…
Twisted domains in ferroelectric nematic liquid crystals
Vladimira Novotna, Lubor Lejcek, Natalia Podoliak
Ferroelectric nematics present properties promising for applications, which strongly depend on the confinement conditions and the presence of defects. In this work, we have observe…
Undulations of smectic A layers in achiral liquid crystals manifested as stripe textures
Natalia Podoliak, Peter Salamon, Lubor Lejček +2
Self-assembly of organic molecules represents a fascinating playground to create various liquid crystalline (LC) nanostructures. In this work, we study layer undulations on microme…
Twist-grain boundary phase characterized by AFM technique
Vladimira Novotna, Lubor Lejcek, Ladislav Fekete
Twist grain boundary (TGB) phases represent liquid crystalline systems with a regular array of defects. In our research, we studied a compound with a stable TGBC phase and establis…
Screw dislocation interaction in smectic-A liquid crystals in an anharmonic approximation
Lubor Lejcek
The interaction of two screw dislocations in smectic-A liquid crystals is treated using an anharmonic correction to the elastic energy density. In the present contribution the elas…
Organic nanotubes created from mesogenic derivatives
Vladimira Novotna, Vera Hamplova, Lubor Lejcek +7
A facile route to prepare the nanotubes from rod-like mesogens dissolved in typical organic solvents is reported. For selected types of chiral rod-like molecules, both enantiomers…
Filaments in the TGBA phase
Lubor Lejcek, Vladimira Novotna, Milada Glogarova
A model of filaments of the TGBA phase arising from the homeotropic smectic A phase and nucleating on the sample surface is proposed. The model is based on the concept of finite bl…
Formation of disclination lines near a free nematic interface
Jordi Ignes-Mullol, Jean Baudry, Lubor Lejcek +1
We have studied the nucleation and the physical properties of a -1/2 wedge disclination line near the free surface of a confined nematic liquid crystal. The position of the disclin…
