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…
