Dechiralisation lines induced unwinding in confined SmC* liquid crystals
B. Mettout, H. Pasco Logbo, H. Vasseur +1
Equilibrium and dynamic behaviors of dechiralisation lines occurring below SmC* cell boundaries in planar geometry consitute a polemic topic for several decades. We report new obse…

Ferrielectricity in smectic-C* dechiralisation lines lattices
B. Mettout, H. Pasco Logbo, Y. Gagou +2
Recent experiments probing a new ferroelectric liquid crystal (CLF08) confined in cells with planar alignment have shown dielectric and optic anomalies suggesting the onset of ferr…

Phenomenological theory of photomagnetoelectric effects Application to the directional photovoltaic effect in LiNbO3
B. Mettout, P. Gisse
We propose a phenomenological theory working out light illumination effects on the equilibrium values of any macroscopic crystal tensor (polarization, magnetization, susceptibiliti…
