Observation of Annihilation Process of Disclinations Emerging from Bubble Domains

Abstract

Dynamics of interacting disclinations is investigated by utilizing bubble domains. A pair of wedge disclinations with strength of +1 and -1 emerge from bubble domains when a suitable electric field is applied, and the density of disclinations can be controlled by adjusting the field. To investigate the interaction between the disclinations, the time evolution is analyzed on the basis of the equation of motion for the disclinations.
