Finite time thermodynamic analysis of quantum Otto heat engine with squeezed thermal bath
چکیده انگلیسی
We investigate the finite time performance of reciprocating quantum Otto heat engine coupled to squeezed hot reservoir. We emphasize the converged limit cycle where each stroke is performed in finite time. To fully exploit the quantum availability provided by the squeezed bath, an optimal frequency protocol in the work extraction stroke is explicitly proposed. The power output is optimized with respect to the hot and cold isochore times. Thermodynamic analysis shows that for a wide range of squeezing parameters, efficiency at maximum power exceeds the generalized Curzon-Ahlborn efficiency defined by the effective temperature of the squeezed bath.
