Nodal statistics of planar random waves

I Nourdin, G Peccati, M Rossi - Communications in Mathematical Physics, 2019 - Springer
We consider Berry's random planar wave model (1977) for a positive Laplace eigenvalue E>
0 E> 0, both in the real and complex case, and prove limit theorems for the nodal statistics …

The number of critical points of a Gaussian field: finiteness of moments

L Gass, M Stecconi - Probability Theory and Related Fields, 2024 - Springer
Let f be a Gaussian random field on R d and let X be the number of critical points of f
contained in a compact subset. A long-standing conjecture is that, under mild regularity and …

Small scale CLTs for the nodal length of monochromatic waves

G Dierickx, I Nourdin, G Peccati, M Rossi - … in Mathematical Physics, 2023 - Springer
We consider the nodal length L (λ) of the restriction to a ball of radius r λ of a Gaussian
pullback monochromatic random wave of parameter λ> 0 associated with a Riemann …

Functional convergence of Berry's nodal lengths: Approximate tightness and total disorder

M Notarnicola, G Peccati, A Vidotto - Journal of Statistical Physics, 2023 - Springer
We consider Berry's random planar wave model (J Phys A 10 (12): 2083–2092, 1977), and
prove spatial functional limit theorems—in the high-energy limit—for discretized and …

Geometry and topology of spin random fields

A Lerario, D Marinucci, M Rossi, M Stecconi - arXiv preprint arXiv …, 2022 - arxiv.org
Spin (spherical) random fields are very important in many physical applications, in particular
they play a key role in Cosmology, especially in connection with the analysis of the Cosmic …

Some recent developments on the geometry of random spherical eigenfunctions

D Marinucci - Proceedings European Congress of Mathematics, 2023 - content.ems.press
A lot of efforts have been devoted in the last decade to the investigation of the high-
frequency behaviour of geometric functionals for the excursion sets of random spherical …

On 3-dimensional Berry's model

F Dalmao, A Estrade, J León - arXiv preprint arXiv:1912.09774, 2019 - arxiv.org
This work aims to study the dislocation or nodal lines of 3D Berry's random wave model.
Their expected length is computed both in the isotropic and anisotropic cases, being them …

Isotropic random spin weighted functions on 𝑆² vs isotropic random fields on 𝑆³

M Stecconi - Theory of Probability and Mathematical Statistics, 2022 - ams.org
We show that an isotropic random field on $ SU (2) $ is not necessarily isotropic as a
random field on $ S^ 3$, although the two spaces can be identified. The ambiguity is due to …

Expectation of a random submanifold: the zonoid section

L Mathis, M Stecconi - arXiv preprint arXiv:2210.11214, 2022 - arxiv.org
We develop a calculus based on zonoids-a special class of convex bodies-for the
expectation of functionals related to a random submanifold $ Z $ defined as the zero set of a …
