Sterle, P. Medle Rupnik, L. Cmok, A. Erkoreka, N. Osterman, A. Mertelj, N. Sebasti\u00e1n) and research groups from University of Leeds (C. J. Gibb, J. Hobbs, R. J. Mandle) and University of the Basque Country (A. Erkoreka, J. Martinez-Perdiguero), has published an article entitled \u201cElasticity-Driven Periodic Polarization Patterns in a Chiral Ferroelectric Nematic Fluid\u201d in Advanced Materials.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">The interplay between chirality, confinement and elasticity can drive the spontaneous formation of complex polarization patterns in chiral ferroelectric nematic liquid crystals. These three factors work together to transform an initially uniform state into a variety of ordered structures.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">In a new study the researchers show that when the pitch of the material under confinement deviates from its natural pitch, periodic instabilities emerge as the material approaches a heliconical polar state. Near such transition, the bend elastic constant of the liquid crystal softens. The combination of the material\u2019s preferred helical structure, confinement and reduced resistance to bending drives the formation of periodic polarization patterns.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Under confinement, these instabilities give rise to a variety of self-organized structures, including stripes, squares and hexagonal patterns. By changing the thickness of the confined material and the surface alignment, the researchers can control which structures emerge. The resulting polarization patterns can also be visualized through their nonlinear optical response using second-harmonic generation imaging. The results demonstrate how chirality, elasticity and geometry can work together to organize polarization in a fluid material. They provide new insight into the physics of ferroelectric nematics and open possibilities for controlling their nonlinear optical properties and developing new self-assembled photonic structures.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>Read the paper at:<\/strong> <a href=\"https:\/\/doi.org\/10.1002\/adma.75002\">https:\/\/doi.org\/10.1002\/adma.75002<\/a> <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Marta Lavri\u010d, in collaboration with a group from Department of Complex Matter F7 (A.
