Transform before linearizing: robust Newton methods for singular -Laplace and -Stokes equations

Gonzalo G. De Diego, Fortino Garcia, Georg Stadler +1

For , the -Laplace equation and its -Stokes generalization are difficult to solve numerically. Newton's method converges rapidly only close to the solution, with itera…

Extensions and Analysis of an Iterative Solution of the Helmholtz Equation via the Wave Equation

Fortino Garcia, Daniel Appelö, Olof Runborg

In this paper we extend analysis of the WaveHoltz iteration -- a time-domain iterative method for the solution of the Helmholtz equation. We expand the previous analysis of energy…

El-WaveHoltz: A Time-Domain Iterative Solver for Time-Harmonic Elastic Waves

Daniel Appelö, Fortino Garcia, Allen Alvarez Loya +1

We consider the application of the WaveHoltz iteration to time-harmonic elastic wave equations with energy conserving boundary conditions. The original WaveHoltz iteration for acou…

Optimal Control of Closed Quantum Systems via B-Splines with Carrier Waves

N. Anders Petersson, Fortino Garcia

We consider the optimal control problem of determining electromagnetic pulses for implementing logical gates in a closed quantum system, where the Hamiltonian models the dynamics o…
