Parity-Time Symmetric Solitons in the Complex KP Equation
arXiv:2304.01562
Abstract
One constructs the parity-time symmetric solitons in the complex KP Equation using the totally non-negative Grassmannian. We obtain that every element in the totally non-negative orthogonal Grassmannian corresponds to a parity-time symmetric solitons solution.
