Summary
Researchers experimentally demonstrated phase synchronization in high-dimensional chaotic oscillators using a thermocapillary convective cell. Localized temperature perturbations induced synchronized states, with transitions studied under varying external influences.
Area of Science:
- Physics
- Nonlinear Dynamics
