Vestigial Nematic Order at Zero Temperature in Two-Dimensional Frustrated Quantum Antiferromagnets
Matthew C. O'Brien, Eduardo Fradkin
The phase diagram of the two-dimensional quantum - Heisenberg antiferromagnet on a square lattice is a long-standing open problem. Despite recent advances in numerical te…

The long-sought pair density wave (PDW) is an exotic phase of matter in which charge density wave (CDW) order is intertwined with the amplitude or phase of coexisting, superconduct…
Electronic structure of topological defects in the pair density wave superconductor
Marcus Rosales, Eduardo Fradkin
Pair density waves (PDWs) are a inhomogeneous superconducting states whose Cooper pairs possess a finite momentum resulting in a oscillatory gap in space, even in the absence of an…
