Black Hole in a Heat Bath
Jarmo Makela
It was recently pointed out by Barrau, Martineau and Renevey that the mass of the Schwarzschild black hole immersed in a heat bath tends to infity in a finite time. We show that th…
Brown-York Energy in Spacetimes with Horizon
Jarmo Mäkelä
We obtain a simple relationship between the change in the Brown-York energy inside of a closed two-surface just outside of a horizon of spacetime, and the change in the area of tha…
Wheeler's It from Bit Proposal in Loop Quantum Gravity
Jarmo Mäkelä
As an attempt to realize Wheeler's "it-from-bit proposal" that physics should be reduced to simple yes-no questions we consider a model of loop quantum gravity, where the only allo…
Phase Transition in Loop Quantum Gravity
Jarmo Mäkelä
We point out that with a specific counting of states loop quantum gravity implies that black holes perform a phase transition at a certain characteristic temperature . In this…
Cosmological Constant as a Free Thermodynamical Variable
Jarmo Mäkelä
We consider a possibility that the cosmological constant may not be a constant, but a free thermodynamical variable. To this end we construct a microscopic model of a spacelike two…
Partition Function of the Schwarzschild Black Hole
Jarmo Mäkelä
We consider a microscopic model of a stretched horizon of the Schwarzschild black hole. In our model the stretched horizon consists of a finite number of discrete constituents. Ass…
Gravitation and Thermodynamics: The Einstein Equation of State Revisited
Jarmo Makela, Ari Peltola
We perform an analysis where Einstein's field equation is derived by means of very simple thermodynamical arguments. Our derivation is based on a consideration of the properties of…
