Noise-specific beats in the higher-level Ramsey curves of a transmon qubit
L. A. Martinez, Z. Peng, D. Appelö +4
In the higher levels of superconducting transmon devices, and more generally charge sensitive devices, measurements made in the presence of low-frequency time-correlated $1…
The Hermite-Taylor Correction Function Method for Maxwell's Equations
Yann-Meing Law, Daniel Appelö
The Hermite-Taylor method, introduced in 2005 by Goodrich, Hagstrom and Lorenz, is highly efficient and accurate when applied to linear hyperbolic systems on periodic domains. Unfo…
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…
Universal AMG Accelerated Embedded Boundary Method Without Small Cell Stiffness
Zhichao Peng, Daniel Appelö, Shuang Liu
We develop a universally applicable embedded boundary finite difference method, which results in a symmetric positive definite linear system and does not suffer from small cell sti…
