Kondo--attractive-Hubbard model for the ordering of local magnetic moments in superconductors
P. R. Bertussi, A. L. Malvezzi, T. Paiva +1
We consider local magnetic moments coupled to conduction electrons with on-site attraction, in order to discuss the interplay between pairing and magnetic order. We probe the groun…
Fermions in 2D Optical Lattices: Temperature and Entropy Scales for Observing Antiferromagnetism and Superfluidity
Thereza Paiva, Richard Scalettar, Mohit Randeria +1
One of the major challenges in realizing antiferromagnetic and superfluid phases in optical lattices is the ability to cool fermions. We determine constraints on the entropy for ob…
Model for spin coupling disorder effects on the susceptibility of antiferromagnetic nanochains
C. M. Chaves, Thereza Paiva, J. d'Albuquerque e Castro +1
The temperature dependence of the static magnetic susceptibility of exchange-disordered antiferromagnetic Heisenberg spin-1/2 finite chains with an odd number of spins is investiga…
