Conical holographic heat engines.

Ahmed, Wasif and Chen, Hong Zhe and Gesteau, Elliott and Gregory, Ruth and Scoins, Andrew (2019) 'Conical holographic heat engines.', Classical and Quantum Gravity, 36 (21). p. 214001.


We demonstrate that adding a conical deficit to a black hole holographic heat engine increases its efficiency; in contrast, allowing a black hole to accelerate decreases efficiency if the same average conical deficit is maintained. Adding other charges to the black hole does not change this qualitative effect. We also present a simple formula to calculate the efficiency of elliptical cycles for any black hole, which allows a more efficient numerical algorithm for computation.
