Competing Pair Density Wave and Uniform -wave Superconductivity in Phase Separated 214 Cuprates at the 1/8 Anomaly
Qiang Chen, Angela Moskal, Yiheng Wang +4
Compelling evidence exists for electronic phase separation in cuprate high- superconductors, emerging near 1/8 hole doping. At these dopings and low temperatures, intertwined…

Computation Kernel for Feynman Diagrams
Daria Gazizova, Rayan Farid, B. D. E. McNiven +3
We present a general representation for solving problems in many-body perturbation theory. By projecting the single-particle Green's function to an auxiliary space we show how one…

Lifshitz transition and triplet -wave pairing from the induced ferromagnetic plaquette via spin differentiated nonlocal interaction
Rayan Farid, Daria Gazizova, B. D. E. McNiven +1
We study the two-dimensional extended Hubbard model on a square lattice and incorporate spin-differentiated nearest neighbor (NN) interactions where the equal-spin () and u…
