Xue-Yang Song, Y.-C. He, A. Vishwanath, and C. Wang

1. From spinon band topology to the symmetry quantum numbers of monopoles in Dirac spMonopole Quantum Numbersin liquids: 

 Phys. Rev. X 10, 011033 (2020)

2. Unifying description of competing orders in two-dimensional quantum magnets

Nature Communications (2019) .

Reviewed in: "Quantum electrodynamics in a piece of rock" by John MacGreevy (UCSD) in Nature Reviews Physics (2019) "Gauge theories, such as quantum electrodynamics, are a cornerstone of high-energy particle physics. They may also describe the physics of certain unassuming materials. Recent theoretical work moves this idea closer to reality."
