Observation of strong electron pairing on bands without Fermi surfaces in LiFe(1-x)CoxAs.
In conventional BCS superconductors, the quantum condensation of superconducting electron pairs is understood as a Fermi surface instability, in which the low-energy electrons are paired by attractive interactions. Whether this explanation is still valid in high-Tc superconductors such as cuprates and iron-based superconductors remains an open question. In particular, a fundamentally different ...
متن کاملFermi surface nesting induced strong pairing in iron-based superconductors.
The discovery of high-temperature superconductivity in iron pnictides raised the possibility of an unconventional superconducting mechanism in multiband materials. The observation of Fermi-surface (FS)-dependent nodeless superconducting gaps suggested that inter-FS interactions may play a crucial role in superconducting pairing. In the optimally hole-doped Ba(0.6)K(0.4)Fe(2)As(2), the pairing s...
متن کاملDeformation of anisotropic Fermi surfaces due to electron - electron interactions
– We analyze the deformations of the Fermi surface induced by electron-electron interactions in anisotropic two dimensional systems. We use perturbation theory to treat, on the same footing, the regular and singular regions of the Fermi surface. It is shown that, even for weak local coupling, the self-energy presents a nontrivial behavior showing momentum dependence and interplay with the Fermi...
متن کاملObservation of a strong atom-dimer attraction in a mass-imbalanced Fermi-Fermi mixture.
We investigate a mixture of ultracold fermionic K40 atoms and weakly bound Li6K40 dimers on the repulsive side of a heteronuclear atomic Feshbach resonance. By radio-frequency spectroscopy we demonstrate that the normally repulsive atom-dimer interaction is turned into a strong attraction. The phenomenon can be understood as a three-body effect in which two heavy K40 fermions exchange the light...

where abg = 63.0 a0 is the background scattering length, ∆ = 0.88 G is the width, and B0 is the center of the resonance near 154.7 G. As we already pointed out in Ref. [2], the optical trap induces a differential light shift between the atom pair state and the molecular state. This leads to a lightinduced shift of the FR center. For the experiments presented in the main text, we use a near-infr...
