Quantum order from string-net condensations and origin of light and massless fermions
Xiao-Gang Wen
Recently, it was pointed out that quantum orders and the associated projective symmetry groups can produce and protect massless gauge bosons and massless fermions in local bosonic…

Possible Z2 phase and spin-charge separation in electron doped cuprate superconductors
Tiago C. Ribeiro, Xiao-Gang Wen
The SU(2) slave-boson mean-field theory for the tt'J model is analyzed. The role of next-nearest-neighbor hopping t' on the phase-diagram is studied. We find a pseudogap phase in h…

Fermions, strings, and gauge fields in lattice spin models
Michael Levin, Xiao-Gang Wen
We investigate the general properties of lattice spin models with emerging fermionic excitations. We argue that fermions always come in pairs and their creation operator always has…
