Ultraslow Oscillation of Nematic Disclination after Abrupt Switching of DC Voltage

Ultraslow Oscillation of Nematic Disclination after Abrupt Switching of DC Voltage

The slow damped oscillation of a nematic disclination was observed after an abrupt (stepwise) change in the DC electric field. The oscillation was not observed under a high-frequency AC field. These results imply that molecular reorientation influences disclination dynamics after abrupt switching. A...

Zusammenfassung:The slow damped oscillation of a nematic disclination was observed after an abrupt (stepwise) change in the DC electric field. The oscillation was not observed under a high-frequency AC field. These results imply that molecular reorientation influences disclination dynamics after abrupt switching. An effective model, which is not a simple elastic theory, was proposed to analyze the results.
