Sub-microsecond electric switching of large birefringence in the isotropic phase of ferroelectric nematics
Kamal Thapa, Sathyanarayana Paladugu, Oleg D. Lavrentovich
Conventional nonpolar nematic liquid crystals, widely known for their successful display applications, are not well-suited for fast electro-optical switching because of the slow (m…
Microsecond electro-optic switching in the nematic phase of a ferroelectric nematic liquid crystal
Kamal Thapa, Sathyanarayana Paladugu, Oleg D. Lavrentovich
Nematic liquid crystals exhibit nanosecond electro-optic response to an applied electric field which modifies the degree of orientational order without realigning the molecular ori…
Electrically tunable total reflection of light by oblique helicoidal cholesteric
Olena S. Iadlovska, Kamal Thapa, Mojtaba Rajabi +3
An oblique helicoidal state of a cholesteric liquid crystal (ChOH) is capable of continuous change of the pitch P in response to an applied electric field. Such a structure reflect…
Confinement and magnetic field effect on chiral ferroelectric nematic in Grandjean-Cano wedge cells
Kamal Thapa, Olena S. Iadlovska, Bijaya Basnet +4
We explore the structure and magnetic field response of edge dislocations in Grandjean-Cano wedge cells filled with chiral mixtures of the ferroelectric nematic mesogen DIO. Upon c…
Soliton walls paired by polar surface interactions in a ferroelectric nematic liquid crystal
Bijaya Basnet, Mojtaba Rajabi, Hao Wang +5
Surface interactions are responsible for many properties of condensed matter, ranging from crystal faceting to the kinetics of phase transitions. Usually, these interactions are po…
In-situ measurements of twist and bend elastic constants in oblique helicoidal cholesteric
Olena S. Iadlovska, Kamal Thapa, Mojtaba Rajabi +2
Unique electro-optical properties of the oblique helicoidal cholesteric (ChOH) stem from its heliconical director structure. An applied electric field preserves the single harmonic…
