We present two schemes to implement the self-contained refrigerator in the framework of the cavity quantum electrodynamics. The considered refrigerators are composed of three interacting microcavities (or two microcavities simultaneously interacting with one three-level atom) separately coupling to a thermal bath with a certain temperature. Despite the local master equation employed, the proposed analytic procedure shows the perfect thermodynamical consistency. It is also demonstrated that the heat is stably extracted from the lowest temperature bath with a fixed efficiency only determined by the intrinsic properties of the refrigerators, i.e., the frequency ratio of the two cavities in contact with the two higher temperature baths. These two schemes indicate that the system with the weak internal coupling in the infinite dimensional Hilbert space can be used to realize the quantum self-contained refrigerator on the principle completely the same as the original self-contained refrigerator.
我们提出了两种在腔量子电动力学框架内实现自给式冰箱的方案。所考虑的冰箱由三个相互作用的微腔（或两个同时与一个三能级原子相互作用的微腔）组成，它们分别与具有一定温度的热库耦合。尽管采用了局部主方程，但所提出的解析过程显示出完美的热力学一致性。还证明了热量以仅由冰箱固有特性决定的固定效率从最低温度热库中稳定提取，即与两个较高温度热库接触的两个腔的频率比。这两种方案表明，在无限维希尔伯特空间中具有弱内部耦合的系统可用于在与原始自给式冰箱完全相同的原理上实现量子自给式冰箱。
