- Authors: Taufiq Murtadho and Sai Vinjanampathy and Juzar Thingna
- Abstract summary: 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.

- Abstract: Synchronization between limit cycle oscillators can arise through entrainment
to an external drive or through mutual coupling. The interplay between the two
mechanisms has been studied in classical synchronizing systems, but not in
quantum systems. Here, we point out that competition and cooperation between
the two mechanisms can occur due to phase pulling and phase repulsion in
quantum systems. We study their interplay in collectively driven degenerate
quantum thermal machines and show that these mechanisms either cooperate or
compete depending on the working mode of the machine (refrigerator or engine).
The entrainment-mutual synchronization interplay persists with an increase in
the number of degenerate levels, while in the thermodynamic limit of
degeneracy, mutual synchronization dominates. Overall, our work investigates
the effect of degeneracy and multilevel scaling of quantum synchronization and
shows how different synchronizing mechanisms can cooperate and compete in
quantum systems.
