Query: Power Fluctuations of An Irreversible Quantum Otto Engine   We derive the general probability distribution function of stochastic work
for quantum Otto engines in which both the isochoric and driving processes are
irreversible due to finite time duration. The time-dependent power
fluctuations, average power, and thermodynamic efficiency are explicitly
obtained for a complete cycle operating with an analytically solvable two-level
system. We show that, there is a trade-off between efficiency (or power) and
power fluctuations.
