Asymmetric butterfly velocities in 2-local Hamiltonians
Yong-Liang Zhang, Vedika Khemani
The speed of information propagation is finite in quantum systems with local interactions. In many such systems, local operators spread ballistically in time and can be characteriz…
Information scrambling in chaotic systems with dissipation
Yong-Liang Zhang, Yichen Huang, Xie Chen
Chaotic dynamics in closed local quantum systems scrambles quantum information, which is manifested quantitatively in the decay of the out-of-time-ordered correlators (OTOC) of loc…
Finite-size scaling of out-of-time-ordered correlators at late times
Yichen Huang, Fernando G. S. L. Brandao, Yong-Liang Zhang
Chaotic dynamics in quantum many-body systems scrambles local information so that at late times it can no longer be accessed locally. This is reflected quantitatively in the out-of…
Out-of-time-ordered correlators in many-body localized systems
Yichen Huang, Yong-Liang Zhang, Xie Chen
In many-body localized systems, propagation of information forms a light cone that grows logarithmically with time. However, local changes in energy or other conserved quantities t…
