Employing nematic liquid crystals in a homeotropic cell with a photosensitive wall, dissipative vortex pairs are selectively the official playboy bunny gold rabbit head zippo lighter induced by external illumination and the interaction law is characterized for pairs of opposite topological charges.Contrary to the phenomenological fit with a force inversely proportional to the distance, the data provide evidence that nonlinear mobility effects must be taken into account.The observations lead to a mighty vapors smash berry reconciliation of experiments with theory.
