    "abstract": "The response of spiral waves to external perturbations in a stable regime of\nthe two-dimensional complex Ginzburg-Landau equation (CGLE) is investigated. It\nis shown that the spiral core has a finite mobility and performs Brownian\nmotion when driven by white noise. Combined with simulation results, this\nsuggests that defect-free and quasi-frozen states in the noiseless CGLE are\nunstable against free vortex excitation at any non-zero noise strength.",
