Russian Doll Renormalization Group and Superconductivity
Andre LeClair, Jose Maria Roman, German Sierra
We show that an extension of the standard BCS Hamiltonian leads to an infinite number of condensates with different energy gaps and self-similar properties, described by a cyclic R…
Anderson transition in low-dimensional disordered systems driven by nonrandom long-range hopping
A. Rodriguez, V. A. Malyshev, G. Sierra +3
The single-parameter scaling hypothesis predicts the absence of delocalized states for noninteracting quasiparticles in low-dimensional disordered systems. We show analytically and…
Kondo Effect in Carbon Nanotube Single-Electron Transistors
Eugene H. Kim, German Sierra, C. Kallin
Recently, Coulomb blockade physics was observed at room temperature in a carbon nanotube single-electron transistor (H. W. Ch. Postma, et. al., Science 293, 76 (2001)). In this wor…
Absence of weak localization in two-dimensional disordered Frenkel lattices
A. Rodriguez, M. A. Martin-Delgado, J. Rodriguez-Laguna +4
The standard one-parameter scaling theory predicts that all eigenstates in two-dimensional random lattices are weakly localized. We show that this claim fails in two-dimensional di…
