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…
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…
