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…
Tracing Primordial Gravitational Waves via non-Gaussian Signatures of Halo Bias
Mariam Abdelaziz, Pritha Bari, Sabino Matarrese +1
Primordial gravitational waves (PGWs) generate scalar density perturbations at second order. Since the induced density contrast is quadratic in the tensor field, it is intrinsicall…
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…
Non-Gaussianity of Tensor Induced Density Perturbations
Mariam Abdelaziz, Pritha Bari, Sabino Matarrese +1
We investigate the non-Gaussianity of second-order matter density perturbations induced by primordial gravitational waves (GWs). These tensor-induced scalar modes arise from local…
