High order splitting method
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 ... WebTo build high order explicit methods, we further note that the -dependence and -dependence in this (,) are product-separable, 2nd and 3rd order explicit symplectic algorithms can be …

WebAug 8, 2012 · Exponential operator splitting methods utilise a natural decomposition of the function defining the right-hand side of the differential equation into (at least) two parts and the presumption that each of the resulting subproblems is solvable in an efficient (and accurate) manner. WebApr 8, 2024 · In this paper, we study high-voltage pulsed electrolysis considering variations in both power converter parameters and cell configuration. Experimental results are obtained for frequency variations ranging from 10 Hz to 1 MHz, voltage changes from 2 V to 500 V, and electrode separations from 0.1 to 2 mm. The results demonstrate that pulsed ...
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. WebJan 6, 2024 · Higher order splitting methods, and reasons why they are not always adopted, are then discussed. Next, we observe that splitting does not capture the correct steady state. This motivates the introduction of balanced splitting: a new splitting method that does preserve the steady state.
