This paper investigates the impact of non-local interactions on the emergence of quantum chaos in Ising spin chains. It compares the behavior of local and non-local Ising models, finding that non-local couplings promote chaos more readily. The study uses level spacing ratios and Krylov complexity to characterize the transition from integrable to chaotic regimes, providing insights into the dynamics of these systems.
Key Takeaways
- •Non-local interactions in Ising models accelerate the onset of quantum chaos.
- •Level spacing ratio and Krylov complexity are used to distinguish between integrable and chaotic phases.
- •Krylov complexity shows a characteristic peak and plateau in chaotic regimes, providing a quantitative measure of chaos.
