Fig. 4: Radial distributions and existence curves of the bulk solitons.
From: Topological bulk solitons in a nonlinear photonic Chern insulator
a, b The radial distributions of the bulk solitons under the self-focusing nonlinearity with g = 1. Power (c) and inverse participation ratio (IPR) (d) of the bulk soliton under the self-focusing nonlinearity with g = 1. Power (e) and IPR (f) of the bulk soliton under the self-defocusing nonlinearity with g = −1. The dashed lines in c–f denote the lower and upper band edges.
