Critical hybridization for the Kondo resonance in gapless systems
R. G. Dias, Lidia del Rio, A. V. Goltsev
We study the Kondo resonance in a spin-1/2 single impurity Anderson model with a gapless conduction band using the equation of motion approach in order to obtain the impurity spect…

Huge metastability in high-T_c superconductors induced by parallel magnetic field
R. G. Dias, J. A. Silva
We present a study of the temperature-magnetic field phase diagram of homogeneous and inhomogeneous superconductivity in the case of a quasi-two-dimensional superconductor with an…
