Eigenstate entanglement in the Sachdev-Ye-Kitaev model
Yichen Huang, Yingfei Gu
We study the entanglement entropy of eigenstates (including the ground state) of the Sachdev-Ye-Kitaev model. We argue for a volume law, whose coefficient can be calculated analyti…
Universal eigenstate entanglement of chaotic local Hamiltonians
Yichen Huang
This arXiv repository is a bundle of two closely related papers. Abstract of the first paper: In systems governed by "chaotic" local Hamiltonians, we conjecture the universality of…
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…
Is microcanonical ensemble stable?
Yichen Huang
No, in a rigorous sense specified below.
Neural network representation of tensor network and chiral states
Yichen Huang, Joel E. Moore
We study the representational power of Boltzmann machines (a type of neural network) in quantum many-body systems. We prove that any (local) tensor network state has a (local) neur…
