Abstract: (923 Views)
A quantum system consisting of two coupled two-level atoms interacting with two-mode quantized field in an optical cavity is studied as a working substance in a quantum Otto cycle, and it has been shown that the system of interest can act as a quantum heat engine. The effect of atom-field coupling strengths during the quantum adiabatic expansion and contraction on the amount of obtained work in the cycle is investigated. We will show that the behavior of the extracted work influenced by the change of the atom-field coupling in the adiabatic stages is different for each of the modes. In addition, the efficiency of the heat engine will be discussed.
