Rheological properties and shear-induced structures of ferroelectric nematic liquid crystals
Ashish Chandra Das, Sathyanarayana Paladugu, Oleg D. Lavrentovich
Recently discovered ferroelectric nematic (NF) liquid crystals are fluids with a polar orientational order. The electric polarization vector can be aligned by an electric field and…
Helix alignment, chevrons, and edge dislocations in twist-bend ferroelectric nematics
Bijaya Basnet, Priyanka Kumari, Sathyanarayana Paladugu +6
We explore surface alignment and edge dislocations in the recently discovered twist-bend ferroelectric nematic, NTBF, in which the vector of spontaneous polarization follows an obl…
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…
Periodic splay Fréedericksz transitions in a ferroelectric nematic
Bijaya Basnet, Sathyanarayana Paladugu, Oleksandr Kurochkin +5
Electric field-induced splay of molecular orientation, called the Fréedericksz transition, is a fundamental electro-optic phenomenon in nonpolar nematic liquid crystals. In a ferro…
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…
Trapping of isotropic droplets by disclinations in nematic liquid crystals controlled by surface anchoring and elastic constant disparity
Nilanthi P. Haputhanthrige, Sathyanarayana Paladugu, Maxim O. Lavrentovich +1
Linear defects such as dislocations and disclinations in ordered materials attract foreign particles since they replace strong elastic distortions at the defect cores. In this work…
