Quantum operator growth bounds for kicked tops and semiclassical spin chains
Chao Yin, Andrew Lucas
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- spins. Focusing on the dy…

Prethermal quasiconserved observables in Floquet quantum systems
Chao Yin, Pai Peng, Xiaoyang Huang +2
Prethermalization, by introducing emergent quasiconserved observables, plays a crucial role in protecting Floquet many-body phases over exponentially long time, while the ultimate…

Bound on quantum scrambling with all-to-all interactions
Chao Yin, Andrew Lucas
We prove bounds on operator growth and infinite temperature out-of-time-ordered correlators in many-body systems with spin- degrees of freedom which interact via t…
