Doping a Mott insulator: Physics of high-temperature superconductivity
TL;DR: In this paper, a review of the physics of high-temperature superconductors from the point of view of the doping of a Mott insulator is presented, with the goal of putting the resonating valence bond idea on a more formal footing.

Doping a Mott Insulator: Physics of High Temperature Superconductivity
TL;DR: In this article, Anderson's idea of the resonating valence bond (RVB) was introduced to describe the spin liquid phase of the undoped Mott insulator, and the slave-boson is introduced to enforce the constraint of no double occupation.
Journal ArticleDOI
Detecting Topological Order in a Ground State Wave Function
Michael Levin,Xiao-Gang Wen +1 more
TL;DR: A way to detect a kind of topological order using only the ground state wave function which directly measures the total quantum dimension D= Sum(id2i).
Journal ArticleDOI
String-net condensation: A physical mechanism for topological phases
Michael Levin,Xiao-Gang Wen +1 more
TL;DR: In this article, it was shown that string-net condensation provides a mechanism for unifying gauge bosons and fermions in 3 and higher dimensions, and the theoretical framework underlying topological phases was revealed.
Journal ArticleDOI
Symmetry protected topological orders and the group cohomology of their symmetry group
Xie Chen,Xie Chen,Zheng-Cheng Gu,Zheng-Xin Liu,Zheng-Xin Liu,Xiao-Gang Wen,Xiao-Gang Wen,Xiao-Gang Wen +7 more
TL;DR: In this paper, it was shown that the boundary excitations of SPT phases can be described by a nonlocal Lagrangian term that generalizes the Wess-Zumino-Witten term for continuous nonlinear σ models.
