[图书][B] The Jaynes–Cummings model and its descendants: modern research directions

J Larson, T Mavrogordatos - 2021 - iopscience.iop.org
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 …

Speed limits and locality in many-body quantum dynamics

CFA Chen, A Lucas, C Yin - Reports on Progress in Physics, 2023 - iopscience.iop.org
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 …

Exponential growth of out-of-time-order correlator without chaos: inverted harmonic oscillator

K Hashimoto, KB Huh, KY Kim, R Watanabe - Journal of High Energy …, 2020 - Springer
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 …

Experimental measurement of out-of-time-ordered correlators at finite temperature

AM Green, A Elben, CH Alderete, LK Joshi… - Physical Review Letters, 2022 - APS
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 …

Krylov complexity for nonlocal spin chains

A Bhattacharya, PP Nath, H Sahu - Physical Review D, 2024 - APS
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 …

Minimal model for fast scrambling

R Belyansky, P Bienias, YA Kharkov, AV Gorshkov… - Physical review …, 2020 - APS
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

C Yin, A Lucas - Physical Review A, 2021 - APS
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

S Kuriyattil, T Hashizume, G Bentsen, AJ Daley - PRX Quantum, 2023 - APS
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 …
