内容記述
内容記述 We construct several new classes of black hole (BH) solutions in the context of the mimetic Euler-Heisenberg theory. We separately derive three differently charged BH solutions and their relevant mimetic forms. We show that the asymptotic form of all BH solutions behaves like a flat spacetime. These BHs, either with or without cosmological constant, have a nonconstant Ricci scalar, due to the contribution of the Euler-Heisenberg parameter, which means that they are not a solution to standard or mimetic f(R) gravitational theory without the Euler-Heisenberg nonlinear electrodynamics and at the same time they are not equivalent to the solutions of the Einstein gravity with a massless scalar field. Moreover, we display that the effect of the Euler-Heisenberg theory makes the singularity of BH solutions stronger compared with that of BH solutions in general relativity. Furthermore, we show that the null and strong energy conditions of those BH solutions are violated, which is a general trend of mimetic gravitational theory. The thermodynamics of the BH solutions are satisfactory although a negative Hawking temperature appears under some conditions. Additionally, these BHs obey the first law of thermodynamics. We also study the stability, using the geodesic deviation, and derive the stability condition analytically and graphically. Finally, for the first time and under some conditions, we derive multihorizon BH solutions in the context of the mimetic Euler-Heisenberg theory and study their related physics.
