High order integrators obtained by linear combinations of symmetric-conjugate compositions
Fernando Casas, Alejandro Escorihuela-Tomàs
A new family of methods involving complex coefficients for the numerical integration of differential equations is presented and analyzed. They are constructed as linear combination…
Applying splitting methods with complex coefficients to the numerical integration of unitary problems
S. Blanes, F. Casas, A. Escorihuela-Tomàs
We explore the applicability of splitting methods involving complex coefficients to solve numerically the time-dependent Schrödinger equation. We prove that a particular class of i…
On symmetric-conjugate composition methods in the numerical integration of differential equations
Sergio Blanes, Fernando Casas, Philippe Chartier +1
We analyze composition methods with complex coefficients exhibiting the so-called ``symmetry-conjugate'' pattern in their distribution. In particular, we study their behavior with…
