Compressible Ferrimagnetism in the depleted Periodic Anderson Model
N. C. Costa, M. V. Araújo, J. P. Lima +3
Tight-binding Hamiltonians with single and multiple orbitals exhibit an intriguing array of magnetic phase transitions. In most cases the spin ordered phases are insulating, while…

A mean-field approach to Kondo-attractive-Hubbard model
N. C. Costa, J. P. Lima, T. C. L. Paiva +2
With the purpose of investigating coexistence between magnetic order and superconductivity, we consider a model in which conduction electrons interact with each other, via an attra…
