Designing Fe Nanostructures at Graphene/h-BN Interfaces
Soumyajyoti Haldar, Pooja Srivastava, Olle Eriksson +2
Tailor-made magnetic nanostructures offer a variety of functionalities useful for technological applications. In this work, we explore the possibilities of realizing Fe nanostructu…
High energy kink in the dispersion of a hole in an antiferromagnet -- double-occupancy effects on electronic excitations
Pooja Srivastava, Saptarshi Ghosh, Avinash Singh
Evolution of the hole spectral function along the Gamma-(pi,pi) cut is studied in the antiferromagnetic state of the Hubbard model. The kink in the calculated hole dispersion, the…
Hole and electron dynamics in the triangular-lattice antiferromagnet -- interplay of frustration and spin fluctuations
Pooja Srivastava, Avinash Singh
Single-particle dynamics in the 120 ordered antiferromagnetic state of the triangular-lattice Hubbard model is studied using a physically transparent fluctuation approach…
Self-energy corrections in an antiferromagnet -- interplay of classical and quantum effects on quasiparticle dispersion
Pooja Srivastava, Avinash Singh
Self-energy corrections due to fermion-magnon interaction are studied in the antiferromagnetic state of the Hubbard model within the rainbow (noncrossing) approximation…
