Modeling quantum heat machines reveals tunable efficiency via the deformation parameter in diatomic molecules, indicating potential for advanced thermal designs.
We present quantum heat machines using a diatomic molecule modelled by a q-deformed potential as a working medium. We analyze the effect of the deformation parameter and other potential parameters on the work output and efficiency of the quantum Otto and quantum Carnot heat cycles. Furthermore, we derive the analytical expressions of work and efficiency as a function of these parameters. Interestingly, our system reveals different operational phases for the range of parameter regimes considered, such as a quantum heat engine. In addition, the efficiency of the quantum Otto heat engine is seen to be tunable by the deformation parameter. Our findings provide useful insight for understanding the impact of anharmonicity on the design of quantum thermal machines.
