Multiple Gaps and Superfluid Density from Interband Pairing in Iron Oxypnictides
L. Benfatto, M. Capone, S. Caprara +2
We study a four-band model for the iron oxypnictides, in which the superconducting properties are assumed to be determined by the interband coupling between hole-like and electron-…
Spectroscopic Signatures of Massless Gap Opening in Graphene
L. Benfatto, E. Cappelluti
Gap opening in graphene is usually discussed in terms of a semiconducting-like spectrum, where the appearance of a finite gap at the Dirac point is accompanied by a finite mass for…
Robustness of the optical-conductivity sum rule in Bilayer Graphene
L. Benfatto, S. G. Sharapov, J. P. Carbotte
We calculate the optical sum associated with the in-plane conductivity of a graphene bilayer. A bilayer asymmetry gap generated in a field-effect device can split apart valence and…
Doping dependence of the vortex-core energy in bilayer films of cuprates
L. Benfatto, C. Castellani, T. Giamarchi
The energy needed to create a vortex core is the basic ingredient to address the physics of thermal vortex fluctuations in underdoped cuprates. Here we theoretically investigate it…
