Nematic twist--bend phase in an external field
Grzegorz Pająk, Lech Longa, Agnieszka Chrzanowska
Nematic twist--bend is the fifth nematic phase recognized in nature. This phase exhibits spiral orientational order, thus it is a chiral structure and it can be stabilized in syste…
In a search for a shape maximizing packing fraction for two-dimensional random sequential adsorption
Michał Cieśla, Grzegorz Pająk, Robert M. Ziff
Random sequential adsorption (RSA) of various two dimensional objects is studied in order to find a shape which maximizes the saturated packing fraction. This investigation was beg…
Twist-bend nematic phases of bent-shaped biaxial molecules
Wojciech Tomczyk, Grzegorz Pająk, Lech Longa
How change in molecular structure can affect relative stability and structural properties of the twist-bend nematic phase (N)? Here we extend the mean-field model [C. G…
Modulated nematic structures induced by chirality and steric polarization
Lech Longa, Grzegorz Pająk
What kind of one-dimensional modulated nematic structures (ODMNS) can form nonchiral and chiral bent-core and dimeric materials? Here, using Landau-deGennes theory of nematics, ext…
Shapes for maximal coverage for two-dimensional random sequential adsorption
Michał Cieśla, Grzegorz Pająk, Robert M. Ziff
The random sequential adsorption of various particle shapes is studied in order to determine the influence of particle anisotropy on the saturated random packing. For all tested pa…
Chiral Symmetry Breaking in Bent-Core Liquid Crystals
Lech Longa, Grzegorz Pająk, Thomas Wydro
By molecular modeling we demonstrate that the nematic long-range order discovered in bent-core liquid crystal systems should reveal further spatially homogeneous phases. Two of the…
Stability of Biaxial Nematic Phase for Systems with Variable Molecular Shape Anisotropy
Lech Longa, Grzegorz Pająk, Thomas Wydro
We study the influence of fluctuations in molecular shape on the stability of the biaxial nematic phase by generalizing the mean field model of Mulder and Ruijgrok [Physica A {\bf…
