CMSA Quantum Matter/Quantum Field Theory Seminar:Modeling the pseudogap state in cuprates: quantum disordered pair density wave
Zhehao Dai - MIT
I will briefly review the pseudogap phenomenology in high Tc cuprate superconductors, especially recent experiments related to charge density waves and pair density waves, and propose a simple theory of the pseudogap. By quantum disordering a pair density wave, we found a state composed of insulating antinodal pairs and a nodal electron pocket. We compare the theoretical predictions with ARPES results, optical conductivity, quantum oscillation and other experiments.
