Black hole evaporation in Lovelock gravity with diverse dimensions

Understand

We investigate the black hole evaporation process in Lovelock gravity with diverse dimensions.

• By selecting the appropriate coefficients, the space-time solutions can possess a unique AdS vacuum with a fixed cosmological constant $\Lambda=-\frac{(d-1)(d-2)}{2\ell^{2}}$.
• The black hole solutions can be divided into two cases: $d>2k+1$ and $d=2k+1$.
• In the case of $d>2k+1$, the black hole is in an analogy with the Schwarzschild AdS black hole, and the life time is bounded by a time of the order of $\ell^{d-2k+1}$, which reduces Page's result on the Einstein gravity in $k=1$.
