Optical Control Of Mass Ejection From Ferroelectric Liquid Droplets: A Possible Tool For The Actuation Of Complex Fluids
Stefano Marni, Raouf Barboza, Annamaria Zaltron +1
We report on the optical control of the recently observed electromechanical instability of ferroelectric liquid droplets exposed to the photovoltaic field of a lithium niobate ferr…

Walk ferroelectric liquid droplets with light
Stefano Marni, Giovanni Nava, Raouf Barboza +2
We show that the motion of ferroelectric liquid sessile droplets deposited on a ferroelectric lithium niobate substrate can be controlled by a light beam of moderate intensity irra…

Pitch tuning induced by optical torque in heliconical cholesteric liquid crystals
G. Nava, F. Ciciulla, O. S. Iadlovska +3
Heliconical cholesteric liquid crystals are expected to be more sensitive to torque induced by light field since their structure allows both bend and twist in molecular orientation…
