Dressed Domain Wall Model of Cuprate Pseudogap

A dressed-domain-wall model of the cuprate pseudogap (arXiv:2303.11254, 2206.00077_v2) captures several features of cuprate physics in a material-specific manner. These include thermodynamic signatures of pseudogap collapse in terms of the collapse of an underlying AFM order, the Fermi arc phenomenon, and the presence of three branches of charge-stripe texture that dominate the intertwined order of the pseudogap. Moreover, two branches of the electronic spectrum delineate a Mott-Slater crossover, where the q-vector of the low-doping branch is controlled by stripe repulsion independent of the Fermi surface (i.e., Mott-like behavior), while the q-vector of the high-doping branch corresponds to (Slater-like) Fermi surface nesting. However, the nesting is not associated with the nonmagnetic Fermi surface, but with the AFM Fermi surface, indicating that the charge stripe order is secondary to the underlying AFM order.
