“…Several attempts were made, such as using a harmonic oscillator as a working substance [8][9][10], utilizing quantum entanglement [11][12][13][14][15], and modifying the thermodynamic cycle [16][17][18]. Exploration of the efficiency of quantum heat engines eventually involves minimal length, which is a topic of discussion in quantum gravity [19].…”

The presence of a minimal length has a significant effect on relativisticphysical systems. This paper discusses how minimal length affects the efficiency of arelativistic quantum heat engine. The working substance chosen is a Dirac particletrapped in a one-dimensional infinite potential well. In this paper, we calculatethe efficiency of a quantum heat engine in three thermodynamic cycles, namely theCarnot, Otto, and Brayton cycles. The engine efficiency is calculated analyticallyand numerically. In this research, the minimal length is a correction factor for therelativistic energy. The result is that the minimal length could increase or decreasethe efficiency of the relativistic quantum heat engine on the small potential widthaccording to the particle mass, the expansion parameter, and the thermodynamiccycle.

“…A wide range of medium substrates for quantum heat engines has been proposed, such as a one-dimensional potential well [1][2][3][4][5], a harmonic oscillator [6][7][8], etc. There have also been studied quantum heat engines with minimal length [9]. For one-dimensional potential well, the efficiency of non-relativistic and relativistic quantum heat engines have been compared.…”

The research on Dirac oscillators has been increasing recently. In this paper, a quantum heat engine by means of a Dirac oscillator that interacts with the external magnetic field is proposed. Relativistic Landau energy levels are used to perform the iso-energetic cycle. The large magnetic field is set to obtain a perfect thermodynamic cycle. Some stable performances at a certain magnitude of magnetic field and expansion parameter range are obtained. When the value of efficiency is compared with the non-relativistic case, an opposite result occurs. Therefore, a quantum heat engine using a Dirac oscillator doesn't govern like a classical oscillator.

A quantum ericson-engine that consists of a single particle with multiple states, has been explored. It is a quantum analogy to the classical ericson-engine consisting of a combination of two isothermal processes and two isobaric processes. By analogizing a particle in a one-dimensional infinite potential well as a gas in a piston-cylinder, quantum thermodynamic processes in a quantum ericson-engine can be explained from the analogies of classical processes such as isothermal, and isobaric. The results of the research show that the thermal efficiency of the quantum ericson-engine has similarities with the classical ericson-engine.
