Benchmarking quantum Stirling and Otto cycles for an interacting spin system

Selçuk Çakmak

A properly selected quantum heat engine consumes resources efficiently. Also, there are many parameters to determine the right option. In this study, we construct and compare the quantum mechanical counterparts of Stirling and Otto cycles for an experimentally achievable quantum working medium where two spins 1/2 interact through isotropic Heisenberg interaction in the tunable external magnetic field. We consider two comparison cases that operate heat cycles with the same system parameters or equal efficiencies. The quantum Stirling cycle produces more work than that of the Otto cycle under the same parameters or equal efficiency conditions. The quantum Stirling engine operates a wider range of coupling strengths. The work performed in the cycles is enhanced by coupling strength. On the other hand, we investigate the role of coupling strength on the performance of the non-regenerative quantum Stirling heat cycle under various magnitudes of the magnetic field. The distance between the applied magnetic fields at the initial and final points of the isothermal stage is found to be an enhancer for the work output and efficiency of the quantum Stirling cycle.

Exploring entanglement effects in a quantum stirling heat engine

H. R. Rastegar Sedehi, Clebson Cruz

Abstract This study presents the development of an entangled quantum Stirling heat engine based on a two-qubit Heisenberg model. We investigate the impact of entangled states of the working substance on the energy exchange and the performance of the Stirling cycle. The results show an improvement in the cycle’s performance, which is accomplished by changing the entangled states. Furthermore, the results suggest that the operational modes of the quantum cycle can be controlled by considering changes in the entangled states of the working material and the temperatures of the reservoirs.

The efficiency of simple Quantum Engine Stirling and Ericsson cycle

Enock Oluwole Oladimeji, Emmanuel Chukwuebuka Umeh, Abamba Oghenetega

The quantum engine cycle serves as an analogous representation of the macroscopic nature of heat engines and the quantum regime of thermal devices composed of a single element. In this work, we follow the formalism of a quantum engine proposed by Bender et al. [1] where they observed quantum Carnot cycle with a single particle of mass m confined to an infinite one-dimensional potential well of width L as a working medium. Using this model, a quantum-mechanical analogue of the Stirling cycle [SC] and Ericsson cycle [EC] have been constructed through changes of both, the width of the well and its quantum state. The efficiency of quantum engines is derived, which is found to be analogous to classical thermodynamic engines. Keywords: Quantum thermodynamics, Quantum mechanics, Ericsson cycle, Stirling cycle, Quantum heat engines, Nano-engines.
