This study models nematic liquid crystals embedded in random polymer networks, where disorder disrupts long-range order and produces a glassy state. It uses simulations and an Imry-Ma-like analytic approach to visualize domains, predict domain size, and calculate the response to an applied electric field. The authors…

This paper theoretically investigates magnetic-field-induced phenomena in bent-core nematic liquid crystals, focusing on how molecular biaxiality modifies the response. Using molecular field and Landau theory, it reproduces reported experimental trends such as an enhanced Cotton-Mouton effect and an increase in the…

This experimental physics study examines how a static electric field affects the optical nonlinearity of methyl-red doped nematic liquid crystals. The authors report that low voltages below the Fredericks transition threshold can change the optical nonlinearity by orders of magnitude. They state that the data fit a…
