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…

Deviation from maximal entanglement for mid-spectrum eigenstates of local Hamiltonians
Yichen Huang
In a spin chain governed by a local Hamiltonian, we consider a microcanonical ensemble in the middle of the energy spectrum and a contiguous subsystem whose length is a constant fr…
