Fermionic representation for the ferromagnetic Kondo lattice model -- diagrammatic study of spin-charge coupling effects on magnon excitations
Sudhakar Pandey, Subrat Das, Bhaskar Kamble +4
A purely fermionic representation is introduced for the ferromagnetic Kondo lattice model which allows conventional diagrammatic tools to be employed to study correlation effects.…

Correlation effects on magnetic frustration in the triangular-lattice Hubbard model
Saptarshi Ghosh, Avinash Singh
Evolution of the magnetic response function in the triangular-lattice Hubbard model is studied with interaction strength within a systematic inverse-degeneracy expansion scheme whi…

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…
