Symmetry protected topological orders and the group cohomology of their symmetry group
(pdf)
Xie Chen, Zheng-Cheng Gu, Zheng-Xin Liu, and Xiao-Gang Wen
arXiv:1106.4772
A short version published in Science338 1604-1606 (2012)
Introduced group cohomology theory into condensed matter physics to describe
short-range entangled phases with symmetry for interacting bosons.
Emergence of helicity +/- 2 modes (gravitons) from qubit models

Zheng-Cheng Gu and Xiao-Gang Wen Nuclear Physics B 863, 90 (2012)
arXiv:0907.1203,
Constructed two quantum spin models on a lattice which gives rise to emergent
gravitons (one with ω = k and the other with ω = k^3 dispersion).
