Strain and spin orbit coupling effects on electronic and optical properties of 2D CX/graphene (X = S, Se, Te) vdW heterostructure for solar energy harvesting
Amit K Bhojani, Hardik L Kagdada, Dheeraj K Singh
Vertically stacked two-dimensional (2D) graphene-based van der Waals (vdW) heterostructures have emerged as the technological materials for electronic and optoelectronic device app…
Semimetallic spin-density wave state in iron pnictides
Garima Goyal, Dheeraj Kumar Singh
We examine the existence of semimetallic spin-density wave states in iron pnictides. In the experimentally observed metallic spin-density wave state, the symmetry-protected Dirac c…
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…
Hund's coupling and electronic anisotropy in the spin-density wave state of iron pnictides
Garima Goyal, Dheeraj Kumar Singh
In the multiband systems, Hund's coupling () plays a significant role in the spin and charge excitations. We study the dependence of electronic anisotropy on in terms of Dru…
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…
Effect of strain-induced orbital splitting on the magnetic excitations in undoped cuprates
Dheeraj Kumar Singh, Yunkyu Bang
We investigate the magnetic excitations in view of the recent reports suggesting that the spin-wave energy may exhibit a significant dependence on the in-plane strain of a thin fil…
