Description:
Author(s): J. Roßnagel, O. Abah, F. Schmidt-Kaler, K. Singer, and E. Lutz We consider a quantum Otto cycle for a time-dependent harmonic oscillator coupled to a squeezed thermal reservoir. We show that the efficiency at maximum power increases with the degree of squeezing, surpassing the standard Carnot limit and approaching unity exponentially for large squeezing paramet... [Phys.
