Quantumness and thermodynamic uncertainty relation of the finite-time Otto cycle

To reveal the role of quantumness in Otto cycle and to discuss validity thermodynamic uncertainty relation (TUR) cycle, we study quantum its classical counterpart. In particular, calculate exactly mean values relative error quantities. quasistatic limit, reduces productivity precision compared that absence quantumness, whereas finite-time mode, it can increase cycle's precision. Interestingly, as strength (heat conductance) between system bath increases, overtakes one. Testing conventional TUR region where entropy production is large enough, find a tighter bound than TUR. However, both cycles violate small. This implies another modified required cover cycle. Finally, possible origin this violation terms products quantities near resonance conditions.
