The effect of side chain length on the mesomorphic properties of ferroelectric nematogens
Natalia Podoliak, Martin Cigl, Pavlo Golub +8
The discovery of ferroelectric nematic phase opened new directions in the field of soft matter chemistry and physics. In this paper, we have modified a previously reported ferroele…
On the emergence of molecular tilt in a ferroelectric smectic liquid crystal with broken director-inversion symmetry
Aitor Erkoreka, Mauricio Vera-Arévalo, Alberto Concellón +5
The origin of some mesophases of the ferroelectric nematic realm is not yet well understood. In this work we study the highly polar liquid crystal MIO, a close structural analogue…
Elasticity-Driven Periodic Polarization Patterns in Confined Chiral Ferroelectric Nematic Fluid
Anej Sterle, Peter Medle-Rupnik, Luka Cmok +9
Ferroelectric nematic phases are a new class of polar fluids in which spontaneous polarization is directly coupled to the orientational order, providing unique opportunities for cr…
Flexoelectricity-driven softening of bend elasticity leads to spontaneous chiral symmetry breaking in a polar fluid
Aitor Erkoreka, Josu Martinez-Perdiguero, Luka Cmok +6
The origin of the recently observed spontaneous chiral symmetry breaking in polar fluids composed of achiral molecules is an unsolved problem, raising fundamental questions about h…
Mean-field theory of the uniaxial ferroelectric smectic A liquid crystal phase
Aitor Erkoreka, Minjung Huang, Satoshi Aya +1
Following the groundbreaking discovery of the ferroelectric nematic liquid crystal phase (NF), a series of closely-related new polar phases have also been found. An especially inte…
Constraining the value of the dielectric constant of the ferroelectric nematic phase
Aitor Erkoreka, Josu Martinez-Perdiguero
Ferroelectric nematic liquid crystals are currently being subject to a plethora of investigations since they are of great fundamental interest and could potentially foster promisin…
A molecular perspective on the emergence of long-range polar order from an isotropic fluid
Aitor Erkoreka, Nerea Sebastián, Alenka Mertelj +1

Dielectric spectroscopy of a ferroelectric nematic liquid crystal and the effect of the sample thickness
Aitor Erkoreka, Josu Martinez-Perdiguero, Richard J. Mandle +2
The recently discovered ferroelectric nematic liquid crystals have been reported to exhibit very large dielectric permittivity values. Here, we report a systematic investigation of…
Collective and non-collective molecular dynamics in a ferroelectric nematic liquid crystal studied by broadband dielectric spectroscopy
Aitor Erkoreka, Alenka Mertelj, Mingjun Huang +3
A great deal of effort has been recently devoted to the study of dielectric relaxation processes in ferroelectric nematic liquid crystals, yet their interpretation remains unclear.…
