GMRES-based multigrid for the complex scaled preconditoner for the indefinite Helmholtz equation
Bram Reps, Wim Vanroose, Hisham bin Zubair
Multigrid preconditioners and solvers for the indefinite Helmholtz equation suffer from non-stability of the stationary smoothers due to the indefinite spectrum of the operator. In…
A preconditioned iterative solver for the scattering solutions of the Schrödinger equation
Hisham bin Zubair, Bram Reps, Wim Vanroose
The Schrödinger equation defines the dynamics of quantum particles which has been an area of unabated interest in physics. We demonstrate how simple transformations of the Schrödin…
Applying numerical continuation to the parameter dependence of solutions of the Schrödinger equation
Jan Broeckhove, Przemysław Kłosiewicz, Wim Vanroose
In molecular reactions at the microscopic level the appearance of resonances has an important influence on the reactivity. It is important to predict when a bound state transitions…
JM-ECS: A hybrid method combining the -matrix and ECS methods for scattering calculations
Y. Bidasyuk, W. Vanroose, J. Broeckhove +2
The paper proposes a hybrid method for calculating scattering processes that combines the -matrix method with exterior complex scaling as an absorbing boundary condition. It rep…
