Fig. 2: Bulk solitons under the self-focusing nonlinearity with g = 1.
From: Topological bulk solitons in a nonlinear photonic Chern insulator
a, b The amplitudes of the two pseudospin components \({\psi }_{1,2}\) of the bulk soliton at K valley. c, d The amplitudes of the two pseudospin components of the bulk soliton at K′ valley. The color bars in a–d denote the amplitudes and the insets in a–d are the phases. The frequencies of the bulk solitons are ω = 9.1.
