A new model of black hole in Lovelock Unique Vacuum theory using the gravitational decoupling method
Year: 2021
Type: preprint
Abstract: We show a new exact solution of black hole for the Lovelock theory with Unique Vacuum (LUV). For this, we provide an extension of the Gravitational Decoupling (GD) algorithm for LUV, which provide a simplest way to solve the equations of motion. As a consequence of the application of the GD, the total mass of black hole varies. Our solution can have up to three horizons: two inner horizons plus the black hole horizon. This horizons structure is a proper characteristic of our solution. The temperature is an increasing function of the black hole horizon and the heat capacity is always positive, {\it i.e.} the solution is stable. Both the horizons structure as the thermodynamics behavior differs from the other black hole solutions previously studied in the literature for LUV.
