Effective highly accurate time integrators for linear Klein-Gordon equations across the scales
Karolina Kropielnicka, Karolina Lademann, Katharina Schratz
We propose an efficient approach for time integration of Klein-Gordon equations with highly oscillatory in time input terms. The new methods are highly accurate in the entire range…
Efficient Magnus-type integrators for solar energy conversion in Hubbard models
Winfried Auzinger, Juliette Dubois, Karsten Held +7
Strongly interacting electrons in solids are generically described by Hubbardtype models, and the impact of solar light can be modeled by an additional time-dependence. This yields…
Solving the linear semiclassical Schrödinger equation on the real line
Arieh Iserles, Karolina Kropielnicka, Katharina Schratz +1
The numerical solution of a linear Schrödinger equation in the semiclassical regime is very well understood in a torus . A raft of modern computational methods are pr…
