Probing Lorentz symmetry violation and topological defects in Euler-Heisenberg black hole through shadows, scalar perturbations, and thermodynamics

In this work, we study a charged black hole incorporating Euler-Heisenberg nonlinear electrodynamics, a global monopole, and spontaneous Lorentz-symmetry breaking generated by a Kalb-Ramond tensor field. We analyze the effects of the model parameters on the spacetime geometry, ph...
