Quasiparticles and c-axis coherent hopping in high T_c superconductors
P. S. Cornaglia, K. Hallberg, C. A. Balseiro
We study the problem of the low-energy quasiparticle spectrum of the extended t-J model and analyze the coherent hopping between weakly coupled planes described by this model. Star…
Mirages and enhanced magnetic interactions in quantum corrals
A. Correa, K. Hallberg, C. A. Balseiro
We develop a theory for the interactions between magnetic impurities in nanoscopic systems. The case of impurities in quantum corrals built on the (111) Cu surface is analyzed in d…
Spectroscopic and magnetic mirages of impurities in nanoscopic systems
K. Hallberg, A. Correa, C. A. Balseiro
We present exact results for magnetic impurities in nanoscopic systems with focusing properties. We analyze the spectroscopic and magnetic properties of Kondo, intermediate valence…
