On the relation between the magnitude and exponent of OTOCs
Yingfei Gu, Alexei Kitaev
We derive an identity relating the growth exponent of early-time OTOCs, the pre-exponential factor, and a third number called "branching time". The latter is defined within the dyn…
A note on the complex SYK model and warped CFTs
Pankaj Chaturvedi, Yingfei Gu, Wei Song +1
We discuss the connections between the complex SYK model at the conformal limit and warped conformal field theories. Both theories have an global symmetry. We…
Fast scrambling on sparse graphs
Gregory Bentsen, Yingfei Gu, Andrew Lucas
Given a quantum many-body system with few-body interactions, how rapidly can quantum information be hidden during time evolution? The fast scrambling conjecture is that the time to…
fractionalized phases of a solvable, disordered, - model
Wenbo Fu, Yingfei Gu, Subir Sachdev +1
We describe the phases of a solvable - model of electrons with infinite-range, and random, hopping and exchange interactions, similar to those in the Sachdev-Ye-Kitaev models…
Entanglement Features of Random Hamiltonian Dynamics
Yi-Zhuang You, Yingfei Gu
We introduce the concept of entanglement features of unitary gates, as a collection of exponentiated entanglement entropies over all bipartitions of input and output channels. We o…
