An effective quantum parameter for strongly correlated metallic ferromagnets
Bhaskar Kamble, Avinash Singh
The correlated motion of electrons in multi-orbital metallic ferromagnets is investigated in terms of a realistic Hubbard model with {\cal N}-fold orbital degeneracy and arbitrary…
Spin-charge and spin-orbital coupling effects on spin dynamics in ferromagnetic manganites
Dheeraj Kumar Singh, Bhaskar Kamble, Avinash Singh
Correlation-induced spin-charge and spin-orbital coupling effects on spin dynamics in ferromagnetic manganites are calculated with realistic parameters in order to provide a quanti…
Orbital fluctuations, spin-orbital coupling, and anomalous magnon softening in an orbitally degenerate ferromagnet
Dheeraj Kumar Singh, Bhaskar Kamble, Avinash Singh
The correlated motion of electrons in the presence of strong orbital fluctuations and correlations is investigated with respect to magnetic couplings and excitations in an orbitall…
Orbital degeneracy, Hund's coupling, and band ferromagnetism: effective quantum parameter, suppression of quantum corrections, and enhanced stability
Bhaskar Kamble, Avinash Singh
An effective quantum parameter is obtained for the band ferromagnet in terms of orbital degeneracy and Hund's coupling. This quantum parameter determines, in analogy with 1/N for t…
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.…
