Pseudogap phenomenon in an ultracold Fermi gas with a p-wave pairing interaction
Pseudogap phenomenon in an ultracold Fermi gas with a p-wave pairing interaction
2012/2/27
We investigate single-particle properties of a one-component Fermi gas with a tunable p-wave interaction. Including pairing fluctuations associated with this anisotropic interaction within a $T$-matri...
Metallic nanograins: spatially nonuniform pairing induced by quantum confinement
Metallic nanograins: spatially nonuniform quantum confinement
2010/11/24
It is well-known that the formation of discrete electron levels strongly influences the pairing in metallic nanograins. Here we focus on another effect of quantum confinement in superconducting grains...

It is developed a microscopic description of superconductivity in ferromagnetic materials with
triplet pairing triggered by the exchange of magnetic fluctuations. Instead widely used paramagnon model...
Pairing Fluctuations Determine Low Energy Electronic Spectra in Cuprate Superconductors
Low Energy Electronic Spectra Cuprate Superconductors
2010/11/24
High-temperature superconductivity in hole-doped cuprates, accompanied by a ‘pseudogap phase’ as well as other strange phenomena, con-tinues to be an outstanding question in condensed matter physics f...
Pairing and Coherence Transition in La1.82Sr0.18CuO4 Strongly Two-Dimensional Superconductor
Fluctuations Transport properties Granularity
2010/9/29
We report conductivity fluctuation measurements in the La1:82Sr0:18CuO4 high temperature superconducting material. The conductivity fluctuation analysis was performed by utilizing the concept of the l...
