Researchers have explored a new class of charged black holes within the framework of Einsteinian cubic gravity (ECG) coupled to Born-Infeld-type electrodynamics. This work establishes the differential equations of motion that describe these novel solutions, expanding our understanding of black hole physics in modified gravity theories and in the presence of nonlinear electromagnetic fields. Einsteinian cubic gravity is a higher-order gravity theory beyond general relativity that includes cubic terms in the Riemann tensor, which can offer a better description of gravity in strong-field regimes.

The study focused on the case of a vanishing bare cosmological constant, a relevant condition as the model is unitary only for asymptotically flat solutions that allow horizons with spherical topology. For these configurations, the thermodynamic quantities of the black holes were calculated, and it was verified that they satisfy the first law of thermodynamics. This compliance is crucial to ensure the physical consistency of the proposed solutions, integrating them within the framework of black hole thermodynamics.

Finally, the authors examined the impact of electric field nonlinearity, electric charge, and the cubic coupling parameter on the local thermal stability of the simulated black holes. This analysis was performed in both canonical and grand canonical ensembles, providing insights into how these intrinsic properties and theory parameters modify the thermodynamic behavior and stability of black holes. The results contribute to the understanding of black hole physics in more complex environments than those described by standard general relativity.
