The RNBHSH contains physically attractive image structures, which include shadows of different sizes in their non-magnetized plasma.

In this series representation, the effective actions give rise to generalized Schrödinger operators on Riemannian manifolds. Each term of the series is a ratio between the determinant of the Laplace–Beltrami operator (plus the mass term) and the aforementioned Schrödinger operators. This ratio represents how the geometry and the disorder fields are interacting to modify the thermodynamic properties of the system, and the modification of the fluctuations introduced by the disorder. The obtained structure allows to construct an entropy which explicitly shows how the introduction of an additive disorder field affects the thermodynamic properties of the black hole.
