Algebraic theory of quantum synchronization and limit cycles under dissipation

B Buča, C Booker, D Jaksch - SciPost Physics, 2022 - scipost.org
Synchronization is a phenomenon where interacting particles lock their motion and display
non-trivial dynamics. Despite intense efforts studying synchronization in systems without …

Measurement-induced continuous time crystals

M Krishna, P Solanki, M Hajdušek, S Vinjanampathy - Physical Review Letters, 2023 - APS
Strong measurements usually restrict the dynamics of measured finite dimensional systems
to the Zeno subspace, where subsequent evolution is unitary due to the suppression of …

Seeding crystallization in time

M Hajdušek, P Solanki, R Fazio, S Vinjanampathy - Physical Review Letters, 2022 - APS
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 …

Topological synchronization of quantum van der Pol oscillators

CW Wächtler, G Platero - Physical Review Research, 2023 - APS
To observe synchronization in large networks of classical or quantum systems demands
both excellent control of the interactions between nodes and very accurate preparation of …

Observation of quantum phase synchronization in a nuclear-spin system

VR Krithika, P Solanki, S Vinjanampathy, TS Mahesh - Physical Review A, 2022 - APS
We report an experimental study of phase synchronization in a pair of interacting nuclear
spins subjected to an external drive in nuclear magnetic resonance architecture. A weak …

Lindbladian approximation beyond ultraweak coupling

T Becker, LN Wu, A Eckardt - Physical Review E, 2021 - APS
Away from equilibrium, the properties of open quantum systems depend on the details of
their environment. A microscopic derivation of a master equation (ME) is therefore crucial. Of …

Role of coherence and degeneracies in quantum synchronization

P Solanki, N Jaseem, M Hajdušek, S Vinjanampathy - Physical Review A, 2022 - APS
Synchronization in quantum systems has been largely driven by specific examples of
frequency entrainment as well as mutual synchronization. Here we study quantum …

Macroscopic quantum synchronization effects

T Nadolny, C Bruder - Physical Review Letters, 2023 - APS
We theoretically describe macroscopic quantum synchronization effects occurring in a
network of all-to-all coupled quantum limit-cycle oscillators. The coupling causes a transition …

Quantum nonstationary phenomena of spin systems in collision models

Y Li, X Li, J ** - Physical Review A, 2023 - APS
We investigate the nonstationary phenomenon in a tripartite spin-1/2 system in the collision
model (CM) framework. After introducing the dissipation through the system-environment …

Analyzing quantum synchronization through Bohmian trajectories

W Li - Physical Review A, 2022 - APS
We analyze quantum effects involved in continuous variable synchronization between two
self-sustaining resonators in the framework of Bohmian mechanics. Bohmian trajectories …
