High-order linearly implicit structure-preserving exponential integrators for the nonlinear Schrödinger equation
Chaolong Jiang, Jin Cui, Xu Qian +1
A novel class of high-order linearly implicit energy-preserving integrating factor Runge-Kutta methods are proposed for the nonlinear Schrödinger equation. Based on the idea of the…
