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…
Thermal evolution of single-particle spectral function in the half-filled Hubbard model and pseudogap
Harun Al Rashid, Dheeraj Kumar Singh
In the half-filled one-orbital Hubbard model on a square lattice, we find pseduogap features in the form of two-peak structures associated with the momentum-resolved spectral funct…
Fermi arcs and pseudogap phase in a minimal microscopic model of -wave superconductivity
Dheeraj Kumar Singh, Samrat Kadge, Yunkyu Bang +1
We show conclusively that a pseudogap state can arise at , for reasonable pairing interaction strength, from order parameter fluctuations in a two dimensional minimal mode…
