Phonon-mediated long-range attractive interaction in one-dimensional cuprates
Establishing a minimal microscopic model for cuprates is a key step towards the elucidation
of a high-T c mechanism. By a quantitative comparison with a recent in situ angle-resolved …

High temperature superconductivity in a lightly doped quantum spin liquid
HC Jiang, SA Kivelson - Physical Review Letters, 2021 - APS
We have performed density-matrix renormalization group studies of a square lattice tJ model
with small hole doping, δ≪ 1, on long four and six-leg cylinders. We include frustration in the …
