CR-Selfdual Cubic Curves

open access: yesMathematics
We introduce a special class of cubic curves whose defining parameter satisfies a linear or quadratic equation provided by the values of a cross ratio. There are only seven such cubics and several properties of the real cubics in this class (some of them

Shielding at a distance due to anomalous resonance

open access: yesNew Journal of Physics, 2017
A cylindrical plasmonic structure with a concentric core exhibits an anomalous localized resonance which results in cloaking effects. Here we show that if the structure has an eccentric core, a new kind of shielding effect can happen.

Elliptic-Möbius S-boxes: A hybrid algebraic construction for cryptographic applications

open access: yesAlexandria Engineering Journal
Substitution boxes (S-boxes) are the nonlinear core of block ciphers, and their design critically impacts resistance against cryptanalytic attacks. Existing approaches either use chaotic maps, which often exhibit structural weaknesses, or elliptic curve (

Conformal structure of FLRW cosmology: spinorial representation and the so $$ \mathfrak{so} $$ (2, 3) algebra of observables

open access: yesJournal of High Energy Physics, 2020
It was recently shown that the homogeneous and isotropic cosmology of a massless scalar field coupled to general relativity exhibits a new hidden conformal invariance under Mobius transformation of the proper time, additionally to the invariance under ...
