• Abstract: We show that the lower levels of a large-spin network with a collective anti-ferromagnetic interaction and collective couplings to three reservoirs may function as a quantum absorption refrigerator. In appropriate regimes, the steady-state cooling current of this refrigerator scales quadratically with the size of the working medium, i.e., the number of spins. The same scaling is observed for the noise and the entropy production rate.

• Performance boost of a collective qutrit refrigerator [0.0]
  A single qutrit with transitions selectively driven by weakly-coupled reservoirs can implement one of the world's smallest refrigerators. We observe a quantum boost, manifest in a quadratic scaling of the steady-state cooling current with $N$. Fine-tuned inter-qutrit interactions may be used to maintain the quantum boost for all $N$ and also for not-perfectly collective scenarios.

  We discuss the onset of quantum chaos and thermalization in the two-mode Dicke model. The two-mode Dicke model exhibits normal to superradiant quantum phase transition. We show that the temporal fluctuations of the expectation value of the collective spin observable around its average are small and decrease with the effective system size.

  We explore a small quantum refrigerator in which the working substance is made of paradigmatic nearest-neighbor quantum spin models. We identify a specific range of interaction strengths which can be tuned appropriately to ensure a cooling of the selected spin. In this domain, when one of the interaction strengths is disordered, the performance of the thermal machine operating as a refrigerator remains almost unchanged.

  We show that quantum absorption refrigerators can be constructed by using three qubits and two thermal baths. One of the qubits attached to the common bath achieves a cooling in the steady state. The proposed refrigerator is shown to provide steady-state cooling for both Markovian qubit-bath interactions between the qubits and canonical bosonic thermal reservoirs.
