title: Kinetic complete wetting of a planar defect close to a bulk tricritical point.
abstract: The nucleation of a new phase at a moving planar defect is considered in the high-symmetry phase of a bulk tricritical point. In the first-order regime a kinetic complete-wetting transition is found where the thickness of the nucleation layer diverges, inducing a change of the drag coefficient of the defect. When the tricritical point is approached, the complete-wetting transition disappears, and, in the adjacent second-order regime, the layer thickness is finite in the full nucleation region.
