Unidirectional charge correlations in hole-doped cuprates
Dheeraj Kumar Singh, Yunkyu Bang
We examine charge correlations and instabilities in the pseudogap phase of high- cuprates modeled by -density wave ordering. The latter has a gap symmetry similar to the on…

Effect of next-nearest neighbor hopping on the single-particle excitations
Harun Al Rashid, Dheeraj Kumar Singh
In the half-filled one-orbital Hubbard model on a square lattice, we study the effect of next-nearest neighbor hopping on the single-particle spectral function at finite temperatur…
