Extended Data Fig. 7: Eccentric fractional skyrmions.
From: Stable singular fractional skyrmion spin texture from the quantum Kelvin–Helmholtz instability
Representative experimental images of showcasing the EFS. At a fixed hold time ts = 60 ms, we repeat the experiment at the same experimental conditions and measure the density profiles of all spin states and spin \(| 1\rangle\) state after two-photon Raman interference. a-e, Longitudinal magnetization, f-j,\(| 0\rangle\) state density, and k-p, interference pattern in the \(| 1\rangle\) state. Images in each column are measured in the same experimental sequence. Yellow boxes represent the same area, and yellow arrows indicate the spin singular point. The mass vorticity is represented in the Y-shaped patterns in (k-p), highlighted with yellow lines.
