Weak cosmic censorship conjecture with pressure and volume in the Gauss-Bonnet AdS black hole

Xiao-Xiong Zeng, Xin-Yun Hu, Ke-Jian He

With the Hamilton-Jacobi equation, we obtain the energy-momentum relation of a charged particle as it is absorbed by the Gauss-Bonnet AdS black hole. On the basis of the energy-mom…
