Giant electroviscous effects in a ferroelectric nematic liquid crystal
M. Praveen Kumar, Jakub Karcz, Przemyslaw Kula +2
The electroviscous effect deals with the change in the viscosity of fluids due to an external electric field. Here, we report experimental studies on the electroviscous effects in…

Dynamics of a sheared twist bend nematic liquid crystal
M. Praveen Kumar, Jakub Karcz, Przemyslaw Kula +1
We study the flow behaviour of a twist-bend nematic liquid crystal. It shows three distinct shear stress () responses in a certain range of temperatures and shear rat…

Smectic-like rheology and pseudo-layer compression elastic constant of a twist-bend nematic liquid crystal
M. Praveen Kumar, P. Kula, Surajit Dhara
In twist-bend nematic (N\textsubscript{TB}) liquid crystals (LCs), the mean molecular orientation exhibits heliconical structure with nanoscale periodicity. On the mesoscopic scale…
