Decoding Quantum Chaos with a Single Scramblon

A combined experiment/theory study using solid-state NMR on a powder of adamantane demonstrates that quantum chaos in a many-body system can be captured by a single scramblon mode. By applying scramblon theory to disentangle intrinsic chaotic scrambling from imperfections in time reversal, researchers extract a quantum Lyapunov exponent and a universal decay parameter, supporting a universal, simple description of chaotic dynamics that could bridge tabletop quantum experiments with holographic gravity concepts.
