Low Residuals, Wrong Value: Learning the Viscosity Solution of Hamilton-Jacobi-Isaacs Equations with PINNs
Raul Jimenez, Pablo Tejerina-Pérez, Leonid Sarieddine +6
Physics-informed neural networks (PINNs) and other residual-trained solvers judge a candidate solution by the size of its sampled PDE residual. For first-order Hamilton-Jacobi equa…
To Stack or Not to Stack? Jacobian Conditioning and the Benefits of Depth in Metasurface-Based Linear Transformation Synthesis
Andrea Abrardo, Andrea Garulli
This paper investigates when and why stacking programmable metasurfaces into Stacked Intelligent Metasurfaces (SIMs) improves linear transformation synthesis at a fixed phase-contr…
Inflation without an Inflaton III: non-Gaussian signatures
Mariam Abdelaziz, Marisol Traforetti, Daniele Bertacca +3
We investigate primordial non-Gaussianity in the Inflation without an Inflaton (IWI) framework, where scalar perturbations are generated at second order by primordial gravitational…
Inflation without an Inflaton II: observational predictions
Marisol Traforetti, Mariam Abdelaziz, Daniele Bertacca +3
We present a complete computation of the scalar power spectrum in the \emph{inflation without inflaton} (IWI) framework, where the inflationary expansion is driven solely by a de~S…
Scalar-Induced Gravitational Waves in Modified Gravity
Anjali Abirami Kugarajh, Marisol Traforetti, Andrea Maselli +2
Scalar-Induced Gravitational Waves (SIGWs), second-order tensor modes sourced by first-order scalar fluctuations in General Relativity (GR), are expected to contribute to the Stoch…
