The statistical properties of the CMB anisotropies, reflecting the curvature inhomogeneities in the early Universe, are very well accounted for by assuming that they emerged from amplified vacuum fluctuations. Being the result of a genuine quantum process, it is natural to wonder which properties of these primordial inhomogeneities are quantum, and which, if any, persisted until their...

Carrollian physics has recently emerged as a powerful framework for describing gravitational subsystems with null boundaries, playing a central role in settings such as flat-space holography and black-hole horizons. In this talk, I will review the development of Carrollian structures, beginning with their algebraic formulation and then connecting it to the geometric viewpoint of null...

In Turing’s study of reaction–diffusion systems, phyllotactic pattern formation was one of his motivations, especially in his later unpublished notes. His work introduced continuous and dynamic approaches to discretely given phyllotactic patterns, inspiring extensive analytical and numerical studies in reaction–diffusion systems. However, Turing himself did not investigate phyllotaxis on...
