Holographic heat engines for Schwarzschild black holes
Ripunjay Dwivedi, Manus R. Visser
We construct reversible black hole heat engines in asymptotically flat spacetime using quasi-local gravitational thermodynamics. We enclose a Schwarzschild black hole in a finite s…
Black hole equations of state and response functions
Silvester G. A. Borsboom, Manus R. Visser
We systematically develop a framework for equilibrium thermodynamics in terms of thermodynamic representations, which are choices of thermodynamic potential and independent variabl…
Holographic pressure and volume for black holes
Silvester Borsboom, Manus R. Visser
We advocate for a holographic definition of thermodynamic pressure and volume for black holes based on quasi-local gravitational thermodynamics. When a black hole is enclosed by a…
Holographic Stirling engines and the route to Carnot efficiency
Nikesh Lilani, Manus R. Visser
We compute the efficiency of the reversible Stirling engine, with and without regeneration, for a broad class of working substances including Van der Waals fluids, quantum ideal ga…
Dynamical entropy of charged black objects
Manus R. Visser, Zihan Yan
We develop a general framework for electromagnetic potential-charge contributions to the first law of black hole mechanics, applicable to dynamical first-order perturbations of sta…
Heat engines for scale invariant systems dual to black holes
Nikesh Lilani, Manus R. Visser
According to holography, a black hole is dual to a thermal state in a strongly coupled quantum system. One of the best-known examples of holography is the Anti-de Sitter/Conformal…
