A generalized Lanczos method for systematic optimization of tensor network states
Rui-Zhen Huang, Hai-Jun Liao, Zhi-Yuan Liu +5
We propose a generalized Lanczos method to generate the many-body basis states of quantum lattice models using tensor-network states (TNS). The ground-state wave function is repres…
Gapless spin-liquid ground state in the kagome antiferromagnet
H. J. Liao, Z. Y. Xie, J. Chen +5
Frustrated quantum magnetism has moved to the forefront of physics research, posing fundamental questions concerning quantum disordered states, entanglement, topology and the natur…
Self-consistent spin-wave analysis of the 1/3 magnetization plateau in the kagome antiferromagnet
Zhong-Chao Wei, Hai-Jun Liao, Jing Chen +6
We propose a modified spin-wave theory to study the 1/3 magnetization plateau of the antiferromagnetic Heisenberg model on the kagome lattice. By the self-consistent inclusion of q…
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…
