Class of exactly solvable SO(n) symmetric spin chains with matrix product ground states
Hong-Hao Tu, Guang-Ming Zhang, Tao Xiang
We introduce a class of exactly solvable SO(n) symmetric Hamiltonians with matrix product ground states. For an odd case, the ground state is a translational invariant Ha…
String order and hidden topological symmetry in the SO(2n+1) symmetric matrix product states
Hong-Hao Tu, Guang-Ming Zhang, Tao Xiang
We have introduced a class of exactly soluble Hamiltonian with either SO(2n+1) or SU(2) symmetry, whose ground states are the SO(2n+1) symmetric matrix product states. The hidden t…
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…
Spin Liquid Phase in Anisotropic Triangular Lattice Heisenberg Model: Exact diagonalization and density-matrix renormalization group calculations
M. Q. Weng, D. N. Sheng, Z. Y. Weng +1
Based on exact diagonalization and density matrix renormalization group (DMRG) method, we show that an anisotropic triangle lattice Heisenberg spin model has three distinct quantum…
Upper Pseudogap Phase: Magnetic Characterizations
Zheng-Cheng Gu, Zheng-Yu Weng
It is proposed that the upper pseudogap phase (UPP) observed in the high-Tc cuprates correspond to the formation of spin singlet pairing under the bosonic resonating-valence-bond (…
Bosonic resonating valence bond wave function for doped Mott insulators
Z. Y. Weng, Y. Zhou, V. N. Muthukumar
We propose a new class of ground states for doped Mott insulators in the electron second-quantization representation. They are obtained from a bosonic resonating valence bond (RVB)…
