Applying splitting methods with complex coefficients to the numerical integration of unitary problems
American Institute of Mathematical Sciences (AIMS) (2022)We explore the applicability of splitting methods involving complex coefficients to solve numerically the time-dependent Schr¨odinger equation. We prove that a particular class of integrators are conjugate to unitary ... -
High order integrators obtained by linear combinations of symmetric-conjugate compositions
Elsevier (2022-02-01)A new family of methods involving complex coefficients for the numerical integration of differential equations is presented and analyzed. They are constructed as linear combinations of symmetric-conjugate compositions ...
