This paper investigates the (semi)group action of on ⁠, a primary example of non-conformal, non-linear, and non-strictly contracting action. We establish variational principles of the affinity exponent for two main examples: the Borel Anosov representations and the Rauzy gasket. In [ 32], they obtain a dimension formula for the stationary measures on ⁠. Combined with our result, it allows us to study the Hausdorff dimension of limit sets of Anosov representations in and the Rauzy gasket.

X-ray radiography is an established diagnostic tool in high-energy-density (HED) physics.1 Its applications range from equation-of-state measurements in dense plasmas,2,3 to laboratory astrophysics,4–7 to inertial confinement fusion (ICF).8 Typically, these methods involve measuring X-ray transmission through the target under study, probing the complex part β of the target’s refractive index n = 1 − δ + iβ.
