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…
Lattice models for non-Fermi liquid metals
Michael Levin, T. Senthil
We present two 2D lattice models with non-Fermi liquid metallic phases. We show that the low energy physics of these models is exactly described by a Fermi sea of fractionalized qu…
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…
Mutual Chern-Simons theory for Z_2 topological order
Su-Peng Kou, Michael Levin, Xiao-Gang Wen
We study several different topological ordered states in frustrated spin systems. The effective theories for those different Z_2 topological orders all have the same form --…
Particle-hole symmetry and the Pfaffian state
Michael Levin, Bertrand I. Halperin, Bernd Rosenow
We consider the properties of the Moore-Read Pfaffian state under particle-hole conjugation. We show that the particle-hole conjugate of the Pfaffian state - or "anti-Pfaffian" sta…
