Abstract
dc.description.abstract
Employing nematic liquid crystals in a homeotropic cell with a
photosensitive wall, dissipative vortex pairs are selectively 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 reconciliation of
experiments with theory.
