Quantum chaos dynamics in long-range power law interaction systems
Xiao Chen, Tianci Zhou
We use out-of-time-order commutator (OTOC) to diagnose the propagation of chaos in one dimensional long-range power law interaction system. We map the evolution of OTOC to a classi…
Operator Dynamics in Brownian Quantum Circuit
Tianci Zhou, Xiao Chen
We explore the operator dynamics in a random -spin model with pairwise interactions (Brownian quanum circuit). We introduce the height of an operator to characterize its spa…
Operator scrambling and quantum chaos
Xiao Chen, Tianci Zhou
Operator scrambling is a crucial ingredient of quantum chaos. Specifically, in the quantum chaotic system, a simple operator can become increasingly complicated under unitary time…
Emergent statistical mechanics of entanglement in random unitary circuits
Tianci Zhou, Adam Nahum
We map the dynamics of entanglement in random unitary circuits, with finite on-site Hilbert space dimension , to an effective classical statistical mechanics, and develop genera…
