Two-bands superconductivity with intra- and interband pairing for synthetic superlattices
Alex A. Schmidt, Jose J. Rodríguez-Núñez, Antonio Bianconi +1
We consider a model for superconductivity in a two-band superconductor, having an anisotropic electronic structure made of two partially overlapping bands with a first hole-like an…
Astrophysical properties of binary star clusters in the Small Magellanic Cloud
J. F. C. Santos, A. A. Schmidt, E. Bica
To study the evolution of binary star clusters we have imaged 7 systems in the Small Magellanic Cloud with SOAR 4-m telescope using B and V filters. The sample contains pairs with…
Vanishing conductivity of quantum solitons in polyacetylene
Leonardo Mondaini, E. C. Marino, A. A. Schmidt
Quantum solitons or polarons are supposed to play a crucial role in the electric conductivity of polyacetylene, in the intermediate doping regime. We present an exact fully quantiz…
BS196: an old star cluster far from the SMC main body
E. Bica, J. F. C. Santos, A. A. Schmidt
We present B and V photometry of the outlying SMC star cluster BS196 with the 4.1-m SOAR telescope. The photometry is deep (to V~25) showing ~3 mag below the cluster turnoff point…
Evidence for a metallic--like state in the T=0 K phase diagram of a high temperature superconductor
A. A. Schmidt, J. J. Rodriguez-Nunez, I. Tifrea
We examine the effects of a phenomenological pseudogap on the T=0 K phase diagram of a high temperature superconductor within a self-consistent model which exhibits a d-wave pairin…
Spin glass freezing in Kondo lattice compounds
Alba Theumann, B. Coqblin, S. G. Magalhaes +1
It is presented a theory that describes a spin glass phase at finite temperatures in Kondo lattice systems with an additional RKKY interaction represented by long range, random cou…
