In the two-component Ginzburg-Landau theory (TCGL) of superfluidity or superconductivity, fractional eddies are regarded as the fundamental type of topological excitation of the theory, and pairs of fractional eddies form a composite type of topological defect, usually called a. increase. Baby skyrmion, or handy skyrmion. In this paper, we study for the first time vortex skyrmion-type topological defects in a class of TCGL-inspired two-component holographic superfluid systems. Two types of skyrmion configurations are constructed: monopole and dipole. We obtain the monople skyrmion by solving the static field equation of motion, and the dipole skyrmion by dynamically unfolding (relaxing) certain initial data using the skyrmion charge. Get As a by-product, such dynamic evolution also confirms the stability of dipolar holographic skyrmions.
