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
The ferroelectric nematic phase (N) has quickly become the most studied system in liquid crystal research. In this work, we investigate the origin of such polar struct…
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…
Fermion-like behavior of elements in their spatial distribution around points of interest
Josu Martinez-Perdiguero
In this paper we analyze the spatial distribution of elements around points of interest. Based on a spatial exclusion principle we model the system by means of a Fermi-Dirac distri…
Development of a high-frequency dielectric spectrometer using a portable vector network analyzer
Aitor Erkoreka, Josu Martinez-Perdiguero
A simple and novel setup for high-frequency dielectric spectroscopy of materials has been developed using a portable vector network analyzer. The measurement principle is based on…
Optimized sample addressing in prism-coupled surface plasmon resonance experiments
Josu Martinez-Perdiguero, Ibon Alonso
In this work we study the walk-off of the beam from the interrogation spot during rotation in surface plasmon resonance experiments using prism-based coupling such as the widesprea…
