Complex Scaling for the Junction of Semi-infinite Gratings

Fruzsina J. Agocs, Tristan Goodwill, Jeremy Hoskins

We present and analyze an integral equation method for the scattering of a non-periodic source from a geometry consisting of two semi-infinite, periodic structures glued together i…

The Well: a Large-Scale Collection of Diverse Physics Simulations for Machine Learning

Ruben Ohana, Michael McCabe, Lucas Meyer +24

Machine learning based surrogate models offer researchers powerful tools for accelerating simulation-based workflows. However, as standard datasets in this space often cover small…

Trapped acoustic waves and raindrops: high-order accurate integral equation method for localized excitation of a periodic staircase

Fruzsina J. Agocs, Alex H. Barnett

We present a high-order boundary integral equation (BIE) method for the frequency-domain acoustic scattering of a point source by a singly-periodic, infinite, corrugated boundary.…

An adaptive spectral method for oscillatory second-order linear ODEs with frequency-independent cost

Fruzsina J. Agocs, Alex H. Barnett

We introduce an efficient numerical method for second order linear ODEs whose solution may vary between highly oscillatory and slowly changing over the solution interval. In oscill…

Quantum initial conditions for curved inflating universes

Mary I. Letey, Zakhar Shumaylov, Fruzsina J. Agocs +3

We discuss the challenges of motivating, constructing, and quantizing a canonically normalized inflationary perturbation in spatially curved universes. We show that this has histor…

Finite inflation in curved space

Lukas T. Hergt, Fruzsina J. Agocs, Will J. Handley +2

We investigate the effects of non-zero spatial curvature on cosmic inflation in the light of cosmic microwave background (CMB) anisotropy measurements from the Planck 2018 legacy r…
