Query: Effects of noise-induced coherence on the performance of quantum
  absorption refrigerators   We study two models of quantum absorption refrigerators with the main focus
on discerning the role of noise-induced coherence on their thermodynamic
performance. Analogously to the previous studies on quantum heat engines, we
find the increase in the cooling power due to the mechanism of noise-induced
coherence. We formulate conditions imposed on the microscopic parameters of the
models under which they can be equivalently described by classical stochastic
processes and compare the performance of the two classes of fridges
(effectively classical vs. truly quantum). We find that the enhanced
performance is observed already for the effectively classical systems, with no
significant qualitative change in the quantum cases, which suggests that the
noise-induced-coherence enhancement mechanism is caused by static interference
phenomena.
