Anomalous BCS equation for a Luttinger superconductor
In the context of the Anderson theory of high Tc cuprates, we develop a BCS theory for Luttinger liquids. If the Luttinger interaction is much stronger than the BCS potential we find that the BCS equation is quite modified compared to usual BCS equation for Fermi liquids. In particular Tc predicted by the BCS equation for Luttinger liquids is quite higher than the usual Tc for Fermi liquids. 1 ...
متن کاملThe BCS - like gap in superconductor
Since the discovery of superconductivity in the cuprates two decades ago, it has been firmly established that the CuO 2 plane is consequential for high T C superconductivity and a host of other very unusual properties. A new family of superconductors with the general composition of LaFeAs(O 1-x F x) has recently been discovered 1-8 but with the conspicuous lacking of the CuO 2 planes, thus rais...
متن کاملComplex spectral evolution in a BCS superconductor, ZrB12
We investigate the electronic structure of a complex conventional superconductor, ZrB12 employing high resolution photoemission spectroscopy and ab initio band structure calculations. The experimental valence band spectra could be described reasonably well within the local density approximation. Energy bands close to the Fermi level possess t2g symmetry and the Fermi level is found to be in the...
متن کاملVorticity and magnetic shielding in a type-II superconductor.
We study in detail, solving the Bogoliubov-de Gennes equations, the magnetic field, supercurrent and order parameter profiles originated by a solenoid or magnetic whisker inserted in a type-II superconductor. We consider solutions of different vorticities, n, in the various cases. The results confirm the connection between the vorticity, the internal currents and the boundstates in a self-consi...
