We study the entropy of static, spherically symmetric black holes in diffeomorphism-invariant theories with nonminimal matter--curvature couplings, using the covariant phase space…
Topological perspective on bulk boundary thermodynamic equivalence
Si-Jiang Yang, Shan-Ping Wu, Shao-Wen Wei +1
We establish an exact duality between the extended thermodynamics of five-dimensional charged Gauss-Bonnet AdS black holes and the thermodynamic framework of the dual boundary conf…
Exact Black Hole Solutions in Bumblebee Gravity with Lightlike or Spacelike VEVS

Dyonic Black Holes in Lorentz-Violating Gravity with a Background Kalb--Ramond Field
Yu-Xuan Lin, Jia-Zhou Liu, Yu-Xiao Liu
By introducing a nonminimal coupling between the Kalb--Ramond field and the electromagnetic field, we construct an exact four-dimensional static, spherically symmetric dyonic black…
