Adding boundary terms to Anderson localized Hamiltonians leads to unbounded growth of entanglement
Yichen Huang
It is well known that in Anderson localized systems, starting from a random product state the entanglement entropy remains bounded at all times. However, we show that adding a sing…
Instability of localization in translation-invariant systems
Yichen Huang, Aram W. Harrow
The phenomenon of localization is usually accompanied with the presence of quenched disorder. To what extent disorder is necessary for localization is a well-known open problem. In…
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…
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…
Efficient simulation of many-body localized systems
Yichen Huang
An efficient numerical method is developed using the matrix product formalism for computing the properties at finite energy densities in one-dimensional (1D) many-body localized (M…
Excited-state entanglement and thermal mutual information in random spin chains
Yichen Huang, Joel E. Moore
Entanglement properties of excited eigenstates (or of thermal mixed states) are difficult to study with conventional analytical methods. We approach this problem for random spin ch…
