Supersolid Order of Frustrated Hard-Core Bosons in a Triangular Lattice System
H. C. Jiang, M. Q. Weng, Z. Y. Weng +2
We numerically demonstrate that a supersolid phase exists in a frustrated hard-core boson system on a triangular lattice over a wide range of interaction strength. In the infinite…
Universal linear-temperature dependence of static magnetic susceptibility in iron-pnictides
Guang-Ming Zhang, Yue-Hua Su, Zhong-Yi Lu +3
A universal linear-temperature dependence of the uniform magnetic susceptibility has been observed in the nonmagnetic normal state of iron-pnictides. This non-Pauli and non-Curie-W…
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…
DMRG Numerical Study of the Kagomé Antiferromagnet
H. C. Jiang, Z. Y. Weng, D. N. Sheng
We numerically study the spin-1/2 antiferromagnetic Heisenberg model on the kagomé lattice using the density-matrix renormalization group (DMRG) method. We find that the ground sta…
On the sign structure of doped Mott insulators
K. Wu, Z. Y. Weng, J. Zaanen
We demonstrate that the sign structure of the t-J model on a hypercubic lattice is entirely different from that of a Fermi gas, by inspecting the high temperature expansion of the…
Phase String Theory for Doped Antiferromagnets
Zheng-Yu Weng
The recent developments of the phase string theory for doped antiferromagnets will be briefly reviewed. Such theory is built upon a singular phase string effect induced by the moti…
