Gravitational lensing in a topologically charged Eddington-inspired Born–Infeld spacetime [PDF]
The European Physical Journal C, 2023 In the present paper, we study several aspects of gravitational lensing caused by a topologically charged Monopole/Wormhole, both in the weak field limit and in the strong field limit.

Reentrant phase transition in holographic thermodynamicsof Born–Infeld AdS black hole [PDF]
The European Physical Journal C, 2022 In this paper, we study the phase tranisions in the extended holographic thermodynamics of Born–Infeld AdS black holes. The extended gravitational thermodynamics of black holes is related to the thermodynamics of the dual field theory by varying both ...

Effects of Born–Infeld electrodynamics on black hole shadows [PDF]
The European Physical Journal C, 2022 In this work, we study the shadow of Born–Infeld (BI) black holes with magnetic monopoles and Schwarzschild black holes immersed in the BI uniform magnetic field. Illuminated by a celestial sphere, black hole images are obtained by using the backward ray-

Observational appearances of magnetically charged black holes in Born–Infeld electrodynamics [PDF]
The European Physical Journal C, 2022 In this paper, we investigate the observational appearances of magnetically charged black holes in Born–Infeld (BI) electrodynamics. We examine the effects of the magnetic charge and the BI parameter on the geodesics with different impact parameters ...

Thick accretion disk configurations in the Born-Infeld teleparallel gravity [PDF]
Physical Review D, 2022 The main goal of this paper is to investigate one of the important astrophysical systems, namely Thick accretion disks, in the background of the spherically symmetric solution in Born-Infeld teleparallel gravity to examine observable predictions of the ...

Hamiltonian birefringence and Born-Infeld limits [PDF]
Journal of High Energy Physics, 2023 Using Hamiltonian methods, we find six relativistic theories of nonlinear electrodynamics for which plane wave perturbations about a constant uniform background are not birefringent. All have the same conformal strong-field limit to Bialynicki-Birula (BB)

Deflection of light by magnetars in the generalized Born–Infeld electrodynamics [PDF]
The European Physical Journal C, 2022 We study the deflection of light by a magnetic dipole field in the generalized Born–Infeld electrodynamics. Using the effective index of refraction and the trajectory equation based on geometric optics, we compute the weak bending angle of light passing ...

Testing Born–Infeld f(T) teleparallel gravity through Sgr $$\hbox {A}^\star $$ observations [PDF]
The European Physical Journal C, 2022 We use observational data from the S2 star orbiting around the Galactic Center to constrain a black hole solution of extended teleparallel gravity models.

Journal of Cosmology and Astroparticle Physics, 2023 We study the Einstein-Klein-Gordon system coupled to the Born-Infeld electrodynamics. We explore the solution space of a static spherically symmetric, complex scalar field minimally coupled to both gravitational and electromagnetic fields.

Emergence of non-linear electrodynamic theories from TT¯-like deformations
Physics Letters B, 2022 In this letter, we investigate the deformation of the ModMax theory, as a unique Lagrangian of non-linear electrodynamics preserving both conformal and electromagnetic-duality invariance, under TT¯-like flows. We will show that the deformed theory is the
