Novel symplectic integrators for the Klein-Gordon equation with space- and time-dependent mass

Bader, Philipp; Blanes Zamora, Sergio; Casas, Fernando; Kopylov, Nikita (Elsevier, 2019-04)

[EN] We consider the numerical time-integration of the non-stationary Klein-Gordon equation with position- and time-dependent mass. A novel class of time-averaged symplectic splitting methods involving double commutators ...
Symplectic integrators for second-order linear non-autonomous equations

Bader, Philipp; Blanes Zamora, Sergio; Casas, Fernando; Kopylov, Nikita; Ponsoda Miralles, Enrique (Elsevier, 2018)

[EN] Two families of symplectic methods specially designed for second-order time-dependent linear systems are presented. Both are obtained from the Magnus expansion of the corresponding first-order equation, but otherwise ...
