Fig. 9: Power-eigenvalue diagrams and power thresholds for solitons in 2D Hatano–Nelson lattices with focusing Kerr nonlinearity.
From: Self-trapping and skin solitons in two-dimensional non-Hermitian lattices
a Power (P)-eigenvalue (μ) diagrams for solitons near the corner (A) and b in the bulk of the lattice. Colored lines correspond to different values of the non-Hermiticity parameter h. c Power thresholds Pth as a function of h, for solitons near the corner (A) (purple line) and in the bulk of the lattice (green line). Black, blue, and red dots correspond to the dots of (a, b), indicating the value of h.
