Gauge Invariant Derivation of Zeroth and First Laws of Black Hole Thermodynamics
K. Hajian, M. M. Sheikh-Jabbari, B. Tekin
In gauge invariant theories, like Einstein-Maxwell theory, physical observables should be gauge invariant. In particular, mass, entropy, angular momentum, electric charge and their…

Extreme Kerr black hole microstates with horizon fluff
K. Hajian, M. M. Sheikh-Jabbari, H. Yavartanoo
We present a one-function family of solutions to 4D vacuum Einstein equations. While all diffeomorphic to the same extremal Kerr black hole, they are labeled by well-defined conser…

Solution Phase Space and Conserved Charges: A General Formulation for Charges Associated with Exact Symmetries
K. Hajian, M. M. Sheikh-Jabbari
We provide a general formulation for calculating conserved charges for solutions to generally covariant gravitational theories with possibly other internal gauge symmetries, in any…
