A simple efficient algorithm in frustration-free one-dimensional gapped systems
Yichen Huang
We propose an efficient algorithm for the ground state of frustration-free one-dimensional gapped Hamiltonians. This algorithm is much simpler than the original one by Landau et al…
Correlation Length versus Gap in Frustration-Free Systems
David Gosset, Yichen Huang
Hastings established exponential decay of correlations for ground states of gapped quantum many-body systems. A ground state of a (geometrically) local Hamiltonian with spectral ga…
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…
Many-body localization with mobility edges
Yichen Huang
We construct a solvable spin chain model of many-body localization (MBL) with a tunable mobility edge. This simple model not only demonstrates analytically the existence of mobilit…
Computing energy density in one dimension
Yichen Huang
We study the problem of computing energy density in one-dimensional quantum systems. We show that the ground-state energy per site or per bond can be computed in time (i) independe…
