Accurate determination of low-energy eigenspectra with multi-target matrix product states
Xuan Li, Zongsheng Zhou, Guanglei Xu +5
Determining the low-energy eigenspectra of quantum many-body systems is a long-standing challenge in physics. In this work, we solve this problem by introducing two novel algorithm…
Umklapp scattering in the one-dimensional Hubbard model
Tong Liu, Kang Wang, Runze Chi +3
The Mott metal-insulator transition is a typical strong correlation effect triggered by the Umklapp scattering. However, in a physical system, the Umklapp scattering coexists with…
Charge dynamics of the antiferromagnetically ordered Mott insulator
X. J. Han, Y. Liu, Z. Y. Liu +5
We study the charge dynamics of the half-filled Hubbard model on the square lattice at zero temperature. We employ a slave-fermion formulation in which the charge degrees of freedo…
Tensor renormalization of quantum many-body systems using projected entangled simplex states
Z. Y. Xie, J. Chen, J. F. Yu +3
We propose a new class of tensor-network states, which we name projected entangled simplex states (PESS), for studying the ground-state properties of quantum lattice models. These…
Second Renormalization of Tensor-Network States
Z. Y. Xie, H. C. Jiang, Q. N. Chen +2
We propose a second renormalization group method to handle the tensor-network states or models. This method reduces dramatically the truncation error of the tensor renormalization…
Accurate determination of tensor network state of quantum lattice models in two dimensions
H. C. Jiang, Z. Y. Weng, T. Xiang
We have proposed a novel numerical method to calculate accurately the physical quantities of the ground state with the tensor-network wave function in two dimensions. We determine…
