Local versus global master equation with common and separate baths: superiority of the global approach in partial secular approximation
Open systems of coupled qubits are ubiquitous in quantum physics. Finding a suitable

Algebraic theory of quantum synchronization and limit cycles under dissipation
Synchronization is a phenomenon where interacting particles lock their motion and display
non-trivial dynamics. Despite intense efforts studying synchronization in systems without …

Synchronizing the smallest possible system
A Roulet, C Bruder - Physical review letters, 2018 - APS
We investigate the minimal Hilbert-space dimension for a system to be synchronized. We
first show that qubits cannot be synchronized due to the lack of a limit cycle. Moving to larger …

Quantum synchronisation enabled by dynamical symmetries and dissipation
In nature, instances of synchronisation abound across a diverse range of environments. In
the quantum regime, however, synchronisation is typically observed by identifying an …

Nonequilibrium transition between dissipative time crystals
We show a dissipative phase transition in a driven nonlinear quantum oscillator in which a

Seeding crystallization in time
We introduce the concept of seeding of crystallization in time by studying the dynamics of an
ensemble of coupled continuous time crystals. We demonstrate that a single subsystem in a …

Cooperation and competition in synchronous open quantum systems
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 …
