Flat limit of artificial cosmology for scalar waves in Schwarzschild-de Sitter
Anıl Zenginoğlu, Govind Arun Kumar
How do cosmological waveforms approximate waveforms from isolated systems for a small cosmological constant? This question is motivated by the observed small value of the cosmologi…
Semilinear wave equations in homothetic hyperboloidal coordinates and tail decay
Anıl Zenginoğlu, Sebastiano Bernuzzi, Andrea Nützi
Late-time wave tails decay at different rates along future null infinity and along timelike worldlines at finite radius. A compactified numerical evolution must represent both the…
Quantum error correction and biological error correction: A structural analogy between qubits and neurons
Ian Whitehouse, Anıl Zenginoğlu, Franz Klein +5
We draw a structural analogy between quantum error correction (QEC) and error handling in neural circuits with respect to their redundant encodings and constraint-based inferences.…
Finite Elements for Helmholtz Scattering with Infinity as a Computational Boundary
Markus Wess, Anıl Zenginoğlu
Building on the null-infinity-layer construction, we develop an H1-conforming finite-element formulation of hyperboloidal compactification for the exterior Helmholtz equation. A ch…
Hyperboloidal evolution for scalar scattering in Minkowski space
Ekrem S Demirboğa, Anıl Zenginoğlu
We develop a time-domain numerical framework for global scalar wave scattering in Minkowski spacetime. The main contribution is an exact conformal matching of three compactified re…
From Penrose to Melrose: Computing Scattering Amplitudes at Infinity for Unbounded Media
Anıl Zenginoğlu
We develop a method to compute scattering amplitudes for the Helmholtz equation in variable, unbounded media with possibly long-range asymptotics. Combining Penrose's conformal com…
