Minimal model for fast scrambling
We study quantum information scrambling in spin models with both long-range all-to-all and
short-range interactions. We argue that a simple global, spatially homogeneous interaction …

Absence of fast scrambling in thermodynamically stable long-range interacting systems
T Kuwahara, K Saito - Physical review letters, 2021 - APS
In this study, we investigate out-of-time-order correlators (OTOCs) in systems with power-law
decaying interactions such as R-α, where R is the distance. In such systems, the fast …

Quantum operator growth bounds for kicked tops and semiclassical spin chains
We present a framework for understanding the dynamics of operator size, and bounding the
growth of out-of-time-ordered correlators, in models of large-S spins. Focusing on the …

Onset of scrambling as a dynamical transition in tunable-range quantum circuits
In a fast-scrambling many-body quantum system, information is spread and entanglement is
built up on a time scale that grows logarithmically with the system size. This is of …
