Structure of the pairing gap from orbital nematic fluctuations
Tomoaki Agatsuma, Hiroyuki Yamase
We study superconducting instability from orbital nematic fluctuations in a minimal model consisting of the and orbitals, and choose model parameters which captur…
Charge-Density-Excitation Spectrum in the t-t'-J-V Model
Andres Greco, Hiroyuki Yamase, Matias Bejas
We study the density-density correlation function in a large-N scheme of the t-t'-J-V model. When the nearest-neighbor Coulomb interaction V is zero, our model exhibits phase separ…
Fermi surface reconstruction and drop of Hall number due to spiral antiferromagnetism in high- cuprates
Andreas Eberlein, Walter Metzner, Subir Sachdev +1
We show that a Fermi surface reconstruction due to spiral antiferromagnetic order may explain the rapid change in the Hall number as recently observed near optimal doping in cuprat…
Plasmon excitations in layered high-Tc cuprates
Andres Greco, Hiroyuki Yamase, Matias Bejas
Motivated by the recent resonant inelastic x-ray scattering (RIXS) experiment for the electron-doped cuprates Nd_{2-x}Ce_{x}CuO_{4} with x around 0.15, we compute the density-densi…
