WebThe split exponential method of solving coupled linear Schrodinger equations (LSBs) has been very valuable in order to treat time-dependent excitation of quantum systems. Thus, ... highly accurate solutions of systems of LSES can be obtained by using high-order split exponential methods [16,17]. Such exponential splitting methods go back to ... WebDec 1, 2024 · This paper presents a high order fast explicit method based on operator splitting and spectral deferred correction (SDC) for solving the nonlocal VCH equation. We start with a second-order operator splitting spectral scheme, which is based on the Fourier spectral method and the strong stability preserving Runge-Kutta (SSP-RK) method.
