Tensor-product representations for string-net condensed states
Zheng-Cheng Gu, Michael Levin, Brian Swingle +1
We show that general string-net condensed states have a natural representation in terms of tensor product states (TPS) . These TPS's are built from local tensors. They can describe…
Tensor-entanglement renormalization group approach to topological phases
Zheng-Cheng Gu, Michael Levin, Xiao-Gang Wen
The tensor-entanglement renormalization group approach is applied to Hamiltonians that realize a class of topologically ordered states -- string-net condensed states. We analyze ph…
Tensor-entanglement renormalization group approach to 2D quantum systems
Zheng-Cheng Gu, Michael Levin, Xiao-Gang Wen
Traditional mean-field theory is a simple generic approach for understanding various phases. But that approach only applies to symmetry breaking states with short-range entanglemen…
Charge dynamics in the phase string model for high-Tc superconductors
Zheng-Cheng Gu, Zheng-Yu Weng
An understanding of the anomalous charge dynamics in the high-Tc cuprates is obtained based on a model study of doped Mott insulators. The high-temperature optical conductivity is…
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 (…
