Absence of temporal order in states with spatial correlation decay
Yichen Huang
In quantum lattice systems, we prove that any stationary state with power-law (or even exponential) decay of spatial correlations has vanishing macroscopic temporal order in the th…

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…

Approximating local properties by tensor network states with constant bond dimension
Yichen Huang
Classical simulation of quantum many-body systems is a fundamental challenge due to their exponentially large Hilbert spaces. Tensor network states are a powerful ansatz to efficie…
