Summary
We observed abnormally high intensity and pulse events in unstable oscillatory media. These events correlate with phase dynamics changes and ±2π phase rotations, offering new insights into complex system behavior.
Area of Science:
- Nonlinear Dynamics
- Complex Systems Physics
- Optical Physics
Background:
- Oscillatory media exhibit complex dynamics under coherent forcing.
- Solitons and roll patterns are common but can become unstable.
- Understanding extreme events in such systems is crucial.
Purpose of the Study:
- Investigate the formation of abnormally high events in spatially extended oscillatory media.
- Connect these events to underlying phase dynamics.
- Explore the role of phase rotations in event generation.
Main Methods:
- Experimental study of oscillatory media dynamics.
- Theoretical analysis of system behavior.
- Focus on phase time trace analysis.
- Examination of phase rotation coexistence.
Main Results:
- Observed abnormally high intensity and pulse height events.
- Identified a link between events and phase slope changes.
- Found correlation between ±2π phase rotations and abnormal events.
- Characterized a regime of instability for solitons and roll patterns.
Conclusions:
- Abnormally high events are linked to phase dynamics shifts.
- Coexisting ±2π phase rotations are associated with these extreme events.
- Findings align with predictions from bidimensional vortex turbulence.
