Extended Data Fig. 5: Simulated and experimentally observed spatial distribution of nucleated skyrmions.
From: Observation of fluctuation-mediated picosecond nucleation of a topological phase
a, Simulated integrated skyrmion count of 1000 skyrmions (10 px diameter) distributed according to a homogeneous nucleation probability in a 100 px diameter field of view. b, 1000 skyrmions distributed with 100 % probability in the central pixel. c, Experimentally observed distribution of optically-nucleated skyrmions (reproduced from Fig. 3 in the main text). d, Experimentally observed distribution of spin–orbit torque nucleated skyrmions (reproduced from24). The horizontal diameters of the fields of view are 100 px in (a) and (b), 1490 nm in (c) and 900 nm in (d). See Supplementary Section 4 for details.
