Accelerating AdS black holes as the holographic heat engines in a benchmarking scheme
We investigate the properties of holographic heat engines with an uncharged
accelerating non-rotating AdS black hole as the working substance in a
benchmarking scheme. We find that the efficiencies of the black hole heat
engines can be influenced by both the size of the benchmark circular cycle and
the cosmic string tension as a thermodynamic variable. In general, the
efficiency can be increased by enlarging the cycle, but is still constrained by
a universal bound as expected. A cross-comparison of the
efficiencies of the accelerating black hole heat engines and Schwarzschild-AdS
black hole heat engines suggests that the acceleration also increases the
efficiency although the amount of increase is not remarkable.Comment: 13 pages,4 figure
Hyperplanes Equipartition with Cascading Makeev
Given a finite number of masses in the Euclidean space, one could ask is it possible to equipartition these masses into equal parts. Fixing the collection of masses, and the amount of hyperplanes, the equipartition-ability depends on the dimension, and there exists a dimension of such equipartition is possible. In this paper, topology and combinatorics method are used for estimating the lower bound and upper bound of the dimension. In particular, we are looking equipartition problem together with Cascading Makeev Constrain
