Time evolution of spread complexity in quenched Lipkin–Meshkov–Glick model
We use the spread complexity (SC) of a time-evolved state after a sudden quantum quench
in the Lipkin–Meshkov–Glick (LMG) model prepared in the ground state as a probe of the …

Fotoc complexity in the Lipkin–Meshkov–Glick model and its variant
N Jaiswal, M Gautam, A Gill, T Sarkar - The European Physical Journal B, 2024 - Springer
We study fidelity out-of-time-order correlators (FOTOCs) in the Lipkin–Meshkov–Glick (LMG)
model and one of its variants dubbed as the extended LMG model. We demonstrate that …
