The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

Experimental progress in atomic, molecular, and optical platforms in the last decade has
stimulated strong and broad interest in the quantum coherent dynamics of many long-range …

We review the mathematical speed limits on quantum information processing in many-body
systems. After the proof of the Lieb–Robinson Theorem in 1972, the past two decades have …

A bstract We provide a detailed examination of a thermal out-of-time-order correlator (OTOC)
growing exponentially in time in systems without chaos. The system is a one-dimensional …

Out-of-time-ordered correlators (OTOCs) are a key observable in a wide range of
interconnected fields including many-body physics, quantum information science, and …

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 …

Building upon recent research in spin systems with nonlocal interactions, this study
investigates operator growth using the Krylov complexity in different nonlocal versions of the …

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 …

Due to the inevitable existence of quantum effects, a classical description generically breaks
down after a finite quantum break‐time tq t_q. We aim to find criteria for determining tq t_q …

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 …
