论文摘要
当功能作为热发动机或冰箱功能时，我们在不同的优化标准下呈现自旋量子奥托机。我们根据热发动机和冰箱的最佳性能，具体取决于其效率，输出功率和最大熵产生。对于热发动机的情况，我们获得了最大功率和最大生态功能的上限和下限效率的表达式。此外，针对三种不同的标准（冷却能力，性能，功率和生态功能的产物）优化了自旋量子奥托冰箱的性能系数。我们进一步研究机器作为加热发动机运行以及冰箱案例的对应物时，冷储液的无限动力损失。我们发现，相对于热（冷）储层频率进行了优化，热发动机（冰箱）周期的最大运行是。
We present the spin quantum Otto machine under different optimization criterion when function either as a heat engine or a refrigerator. We examine the optimal performance of the heat engine and refrigerator depending on their efficiency, output power and maximum entropy production. For heat engine case, we obtain the expression for the upper and lower bounds efficiencies at maximum power and maximum ecological function. In addition, the spin quantum Otto refrigerator coefficient of performance is optimized for three different criterion -- cooling power, product of performance and power and ecological function. We further study the dimensionless power loss to the cold reservoir when the machine is operating as a heat engine as well as its counterpart for the refrigerator case. We find that the maximum operation of the heat engine (refrigerator) cycle is when optimized with respect to hot (cold) reservoir frequency.
