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

2017-11-17T10:00:00+00:00

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...

Mapping of the Bak, Tang, and Wiesenfeld sandpile model on a two-dimensional Ising-correlated percolation lattice to the two-dimensional self-avoiding random walk

Author(s): J. Cheraghalizadeh, M. N. Najafi, H. Dashti-Naserabadi, and H. Mohammadzadeh

The self-organized criticality on the random fractal networks has many motivations, like the movement pattern of fluid in the porous media. In addition to the randomness, introducing correlation between the neighboring portions of the porous media has some nontrivial effects. In this paper, we consi...
