Enabling the self-contained refrigerator to work beyond its limits by filtering the reservoirs


Author(s): Zi-chen He, Xin-yun Huang, and Chang-shui Yu

In this paper, we study the quantum self-contained refrigerator [Linden et al., Phys. Rev. Lett. 105, 130401 (2010)] 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 wor...
