Checkerboard superconducting order and antinodal Bogoliubov quasiparticle interference

V. I. Belyavsky, V. V. Kapaev, Yu. V. Kopaev

Numerical study of momentum-dependent gap function is presented to make clear the origin of superconductivity in copper oxides. We claim that antinodal region with pronounced nesti…

Percolative nature of the transition from 60 K to 90 K phase in YBa2Cu3O6+d

S. Yu. Gavrilkin, O. M. Ivanenko, V. P. Martovitskii +2

We have measured the heat capacity of YBa2Cu3O6+d for 0.7<d<0.8 between 1.8 and 300K. It was found that doping dependences of specific heat jump and temperature of heat capacity ju…

Fermi arcs as a visible manifestation of pair level of negative-U centers

K. V. Mitsen, O. M. Ivanenko

Here we consider the possibility that the Fermi arcs observed in ARPES experiments result from interaction of valence band electrons with negative-U centers (NUCs) which are formed…

Point-contact Andreev-reflection spectroscopy in ReFeAsO_{1-x}F_x (Re = La, Sm): Possible evidence for two nodeless gaps

R. S. Gonnelli, D. Daghero, M. Tortello +6

A deep understanding of the character of superconductivity in the recently discovered Fe-based oxypnictides ReFeAsO1-xFx (Re = rare-earth) necessarily requires the determination of…

Non-local Andreev reflection under ac bias

D. S. Golubev, A. D. Zaikin

We theoretically analyze non-local electron transport in multi-terminal normal-metal-superconductor-normal-metal (NSN) devices in the presence of an external ac voltage bias. Our a…
