Development of New Thermodynamic Cycles [PDF]

open access: yes, 2002
In general, optimization is a way to find the best solution to a problem of any kind. We do a lot of optimization in our daily life. For example, we always search for the best product, which meets our demands, with the lowest possible price. In engineering, optimization is a very powerful tool.

Accelerating AdS black holes as the holographic heat engines in a benchmarking scheme

open access: yes, 2018
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

Harnessing Outer Space for Improved Electrocaloric Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...

Quantum engine based on many-body localization [PDF]

open access: yes, 2019
Many-body-localized (MBL) systems do not thermalize under their intrinsic dynamics. The athermality of MBL, we propose, can be harnessed for thermodynamic tasks.

Loose mechanochemical coupling of molecular motors

open access: yes, 2011
In living cells, molecular motors convert chemical energy into mechanical work. Its thermodynamic energy efficiency, i.e. the ratio of output mechanical work to input chemical energy, is usually high.
