Coherence Temperature in the Diluted Periodic Anderson Model
N. C. Costa, T. Mendes-Santos, T. Paiva +3
The Kondo and Periodic Anderson Model (PAM) are known to provide a microscopic picture of many of the fundamental properties of heavy fermion materials and, more generally, a varie…

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…

Impurities near an Antiferromagnetic-Singlet Quantum Critical Point
T. Mendes, N. Costa, G. Batrouni +4
Heavy fermion systems, and other strongly correlated electron materials, often exhibit a competition between antiferromagnetic (AF) and singlet ground states. Using exact Quantum M…
