- W1987116503 abstract "We measure the electric-field-driven annihilation of nematic disclination pairs with strength $ifmmodepmelsetextpmfi{}1/2$ in the $4mathrm{text{ensuremath{-}}}mathrm{text{cyano}}mathrm{text{ensuremath{-}}}{4}^{ensuremath{'}}mathrm{text{ensuremath{-}}}n$-pentylbiphenyl (5CB) liquid crystal. The use of a very weak azimuthal anchoring ensures a two-dimensional director field. The relaxation is governed by the formation of a $ensuremath{pi}$ wall connecting the two opposite charge defects. The $+1/2$ disclinations move almost twice as fast as the $ensuremath{-}1/2$ disclinations. The simple used geometry allows a quantitative comparison with numerical studies based on the hydrodynamics of the tensorial order parameter. The simulations show that in the $ensuremath{pi}$ wall regime the symmetry breaking is due to the backflow and not to the elastic anisotropy." @default.
