Ferroelectric nematic -- isotropic critical end point
Jadwiga Szydlowska, Pawel Majewski, Mojca Čepič +8
A critical end point above which an isotropic phase continuously evolves into a polar (ferroelectric) nematic phase with an increasing electric field is found in a ferroelectric ne…
Dielectric response of a ferroelectric nematic liquid crystalline phase in thin cells
Nataša Vaupotič, Damian Pociecha, Paulina Rybak +4
We studied dielectric properties of a polar nematic phase (NF) sandwiched between two gold or ITO electrodes, serving as a cell surfaces. In bulk, NF is expected to exhibit a Golds…
Liquid crystals: a new topic in physics for undergraduates
Jerneja Pavlin, Natasa Vaupotic, Mojca Cepic
The paper presents a teaching module about liquid crystals. Since liquid crystals are linked to everyday student experiences and are also a topic of a current scientific research,…
Direction dependency of extraordinary refraction index in uniaxial nematic liquid crystals
Jerneja Pavlin, Natasa Vaupotic, Mojca Cepic
The article presents a straightforward experiment that directly and illustratively demonstrates double refraction. For this purpose, two liquid crystalline cells were designed, whi…
Effect of optical purity on phase sequence in antiferroelectric liquid crystals
Natasa Vaupotic, Mojca Cepic
We use the discrete phenomenological model to study theoretically the phase diagrams in antiferroelectric liquid crystals (AFLCs) as a function of optical purity and temperature. R…
Switching mechanism in polar columnar mesophases made of bent-core molecules
Ewa Gorecka, Natasa Vaupotic, Damian Pociecha +2
The behavior of polar columnar phases made of bent shaped molecules (B_1Rev and B_1RevTilted) was studied under applied electric field. There are two competing mechanisms of switch…
