In this paper, we study the quantum self-contained refrigerator [Linden et al., Phys. Rev. Lett. 105, 130401 (2010)PRLTAO0031-900710.1103/PhysRevLett.105.130401] in the strong internal coupling regime with engineered reservoirs. We find that if some modes of the three thermal reservoirs can be properly filtered out, the efficiency and the working domain of the refrigerator can be improved in contrast to the those in the weak internal coupling regime, which indicates one advantage of the strong internal coupling. In addition, we find that the background natural vacuum reservoir could cause the filtered refrigerator to stop working and the background natural thermal reservoir could greatly reduce the cooling efficiency.
在本文中，我们研究了强内耦合环境下带有工程热库的量子自维持冰箱[Linden 等人，Phys. Rev. Lett. 105, 130401 (2010)PRLTAO0031-900710.1103/PhysRevLett.105.130401]。我们发现，如果三个热库中的某些模式能够被适当过滤掉，与弱内耦合环境相比，冰箱的效率和工作范围将会得到提高，这表明了强内耦合的一个优势。此外，我们发现背景自然真空热库会导致过滤后的冰箱停止工作，而背景自然热库会大大降低冷却效率。
