Quantum signatures in a quadratic optomechanical heat engine with an atom in a tapered trap

We investigate how quantum signatures can emerge in a single atom heat engine consisting of an confined tapered trap and subjected to hot cold thermal reservoirs. A similar system was realized experimentally Science 352 , 325 ( 2016 ) SCIEAS 0036-8075 10.1126/science.aad6320 . model such using quadratic optomechanical identify effective Otto cycle the system’s dynamics. compare engine’s performance classical regimes by evaluating power dissipated. find that lowering temperature is insufficient make genuine quantum-enhanced engine. show it necessary more asymmetric ensure correlations cause enhancement output.
