Description
We propose a two-body variant of bosonic SYK-type models that represents a minimal setting in which chaotic dynamics emerge, a phenomenon we refer to as quadratic quantum chaos. In contrast to integrable quadratic fermionic systems, the corresponding hard-core bosonic models exhibit genuine many-body chaos. We diagnose this behaviour using spectral statistics and multiple probes of operator growth. Owing to their simplicity and bosonic nature, these minimal models provide promising and resource-efficient platforms for investigating quantum chaos and information scrambling on near-term quantum devices.
