Theoretical and experimental studies on thermoelectricity transport in Nano scale device is in spot light of Physics throughout the world due to its direct and efficient possibility of thermoelectric transformation. Furthermore, many attempts to enhance the performance of thermoelectric transport are made using additional quantum dynamic phenomena such as Cooper Pair Splitting.
Cooper Pair Splitting (CPS) is the process that Cooper pair splits into two electrons through the QDs(Quantum Dots) which have various couplings to superconductors, while maintaining their entanglement state. The researches on the Cooper Pair Splitting effect, which made its first start in the quantum information theory and was focused the powerful candidate for nonlocal entangled electrons, is now widely carried out in various fields and introduced in the development of hi-fi quantum heat engine. Since the discovery of topological phase of substance, it's considered the best concern of not only theorists but also experimental scientists in condensed state of physics for the scope of topological insulators and superconductors being enlarged.
Obviously, there are many parameters such as Elastic Cotunneling (EC) process, temperature difference, energy level of QDs, chemical potential differences between opponent leads and etc., to do with the performance of quantum heat engine induced by CPS. Therefore, it is very important to clarify the optimal performance of quantum heat engine induced by CPS through detailed investigation of various parameters mentioned above.
To this end, optimization programs should be introduced. Recently, we have studied the optimal performance of quantum heat engine induced by CPS in detail, depending on multi-objective genetic algorithm. In the scheme of Master equation, we have studied the power and efficiency properties of quantum heat engine to get the optimal solutions of this engine in terms of various parameters. Our results have been suggested as the pareto optimal solutions, so each solution has its own advantage and which one to choose depends on the decisions of engineers or designers.
The result has been published in "Physica B 654, 414682, 2023" under the title of "Optimal thermoelectric induced by Cooper pair splitting"(https://doi.org/10.1016/j.physb.2023.414682).
