Quantum Scarring

Quantum scarring is a phenomenon where certain quantum systems, especially those that are classically chaotic, exhibit unexpectedly intense patterns along the paths of specific classical trajectories. In essence, even in complex, unpredictable environments, some quantum states remain surprisingly concentrated along these paths, creating visible “scars” in their probability distributions. This shows a surprising link between the predictable rules of classical physics and the probabilistic nature of quantum mechanics, revealing how classical behavior can influence quantum systems in subtle and intriguing ways.
