Chaos and multifold complexity for an inverted harmonic oscillator
Le-Chen Qu, Hong-Yue Jiang, Yu-Xiao Liu
We examine the multifold complexity and Loschmidt echo for an inverted harmonic oscillator. We give analytic expressions for any number of precursors, implementing multiple backwar…

Chaos and Complexity for Inverted Harmonic Oscillators
Le-Chen Qu, Jing Chen, Yu-Xiao Liu
We investigate the circuit complexity and Loschmidt echo for the (inverted) harmonic oscillators. Focusing on the chaotic behaviors under the perturbation, we analytically derive t…
