Chiral ferroelectric nematic liquid crystals as materials for versatile laser devices

César L. Folcia, Josu Ortega, Teresa Sierra +2

We present a liquid-crystal laser device based on the chiral ferroelectric nematic phase (NF*). The laser medium is obtained by mixing a ferroelectric nematic material with a chira…

Generalization of the Maier-Saupe theory to the ferroelectric nematic phase

J. Etxebarria, C. L. Folcia, J. Ortega

We present a generalization of the Maier-Saupe (MS) theory that incorporates the description of the ferroelectric nematic phase (NF) within its scope of application. The extension…
