Volume dependent extension of Kerr-Newman black hole thermodynamics
Tamás S. Biró, Viktor G. Czinner, Hideo Iguchi +1
We show that the Hawking--Bekenstein entropy formula is modified by a factor of if one also considers a work term in the 1st law of thermodynamics by a pressure stemming from…

Black hole horizons can hide positive heat capacity
Tamás S. Biró, Viktor G. Czinner, Hideo Iguchi +1
Regarding the volume as independent thermodynamic variable we point out that black hole horizons can hide positive heat capacity and specific heat. Such horizons are mechanically m…
