A Convergent Three-Step Numerical Method to Solve a Double-Fractional Two-Component Bose–Einstein Condensate Serna Reyes, Adán J. Macías Díaz, Jorge E. Reguera López, Nuria Two-component Bose-Einstein condensate Double-fractional system Numerically efficient scheme This manuscript introduces a discrete technique to estimate the solution of a doublefractional two-component Bose–Einstein condensate. The system consists of two coupled nonlinear parabolic partial differential equations whose solutions are two complex functions, and the spatial fractional derivatives are interpreted in the Riesz sense. Initial and homogeneous Dirichlet boundary data are imposed on a multidimensional spatial domain. To approximate the solutions, we employ a finite difference methodology. We rigorously establish the existence of numerical solutions along with the main numerical properties. Concretely, we show that the scheme is consistent in both space and time as well as stable and convergent. Numerical simulations in the one-dimensional scenario are presented in order to show the performance of the scheme. For the sake of convenience, A MATLAB code of the numerical model is provided in the appendix at the end of this work. 2023-11-09T09:05:02Z 2023-11-09T09:05:02Z 2021-06 info:eu-repo/semantics/article http://hdl.handle.net/10259/7967 10.3390/math9121412 2227-7390 eng Mathematics. 2021, V. 9, n. 12, 1412 https://doi.org/10.3390/math9121412 http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Atribución 4.0 Internacional MDPI
