• Abstract summary: We study the relationship between quantum synchronization and the thermodynamic performance of a four-level near-degenerate extension of the Scovil-Schulz Dubois thermal maser. We show how the existence of interacting coherences can potentially modify the relationship between synchronization and the coherent power output of such a maser.

• Abstract: We study the relationship between quantum synchronization and the thermodynamic performance of a four-level near-degenerate extension of the Scovil-Schulz Dubois thermal maser. We show how the existence of interacting coherences can potentially modify the relationship between synchronization and the coherent power output of such a maser. In particular, the cooperation and competition between interacting coherences, causes the coherent heat and efficiency to be bounded by the synchronization measure in addition to the well-studied power synchronization bound. Overall, our results highlight the role of quantum synchronization in the working of a thermal machine.

  We show that competition and cooperation between the two mechanisms can occur due to phase pulling and phase repulsion in quantum systems. The interplay persists with an increase in the number of degenerate levels, while in the thermodynamic limit of degeneracy, mutual synchronization dominates.

  Recent predictions for quantum-mechanical enhancements in the operation of small heat engines have raised renewed interest. One essential question is whether collective effects may help to carry enhancements over larger scales. We study how power, efficiency and constancy scale with the number of spins composing the engine.

  We explore a prototype of an oscillatory neural network (ONN) based on vanadium dioxide switching devices.

In the case of a strong thermal coupling, the limit of the supply current parameters, for which the oscillations exist, expands by 10 %. The effect of subharmonic synchronization hold promise for application in classification and pattern recognition.
