We present a general review of the projective symmetry group classification of fermionic
quantum spin liquids for lattice models of spin S= 1/2. We then introduce a systematic …

We present an exact ground state solution of a quantum dimer model introduced by Punk,
Allais, and Sachdev [Quantum dimer model for the pseudogap metal, Proc. Natl. Acad. Sci …

To capture various experimental results in the pseudogap regime of the underdoped cuprate
superconductors for temperature T< T*, we propose a four-component pair density wave …
