  title={Charged 4D Einstein-Gauss-Bonnet black hole: Vacuum solutions, Cauchy horizon, thermodynamics},
  author={M. Bousder and Khadija El Bourakadi and Mohamed Bennai},
In this paper, we investigate the four-dimensional Einstein-Gauss-Bonnet black hole. The thermodynamic variables and equations of state of black holes are obtained in terms of a new parameterization. We discuss a formulation of the van der Waals equation by studying the effects of the temperature on P −V isotherms. We show the influence of the Cauchy horizon on the thermodynamic parameters. We prove by different methods, that the black hole entropy obey area law (plus logarithmic term that… Expand

Charged black holes in AdS spaces in 4D Einstein Gauss-Bonnet gravity
Abstract Recently a non-trivial 4-dimensional theory of gravity that claims to circumvent Lovelock's theorem and avoid Ostrogradsky instability was formulated in Glavan and Lin (2020) [1] . ThisExpand
Particle-antiparticle in 4D charged Einstein-Gauss-Bonnet black hole
We study the charge of the 4D-Einstein-Gauss-Bonnet black hole by a negative charge and a positive charge of a particle-antiparticle pair on the horizons r− and r+, respectively. We show that thereExpand
