Investigating soliton solutions in a 2D Hatano-Nelson lattice, highlighting non-Hermiticity's role and power thresholds.
We investigate the interplay between Kerr nonlinearity and non-Hermiticity in a 2D Hatano-Nelson lattice under single-channel excitation, identifying power thresholds, self-focusing regions, and localized soliton solutions across the lattice.
