Efficient Adaptive Computation of the Dynamics of Mott Transistors
Winfried Auzinger, Lukas Einramhof, Karsten Held +4
We investigate time-adaptive Magnus-type integrators for the numerical approximation of a Mott transistor. The rapidly attenuating electromagnetic field calls for adaptive choice o…

Line Integral Solution of Hamiltonian Systems with Holonomic Constraints
Luigi Brugnano, Gianmarco Gurioli, Felice Iavernaro +1
In this paper, we propose a second-order energy-conserving approximation procedure for Hamiltonian systems with holonomic constraints. The derivation of the procedure relies on the…
