Interference Patterns Control Chaotic Movement Within Quantum Oscillators

Umair Abdul Halim at UPM Serdang and colleagues demonstrate that the extent of chaos directly correlates with the temporal coherence of interfering oscillator modes. Their analysis reveals that near resonance, sustained interference creates expansive chaotic regions, while sharp frequency detuning restricts chaotic behaviour to smaller areas. The research provides a coherence parameter as a key set of tools for understanding chaotic transport in similar low-dimensional Bohmian systems, potentially advancing the design and control of quantum systems. The dimensionless coherence parameter, χ, now accurately predicts the extent of chaotic motion, improving upon prior methods reliant on incommensurate frequency ratios that masked results with dephasing. Traditionally, the…
