Observation of quantum corrections to conductivity up to optical frequencies
P. Neilinger, J. Greguš, D. Manca +6
It is well known that conductivity of disordered metals is suppressed in the limit of low frequencies and temperatures by quantum corrections. Although predicted by theory to exist…
What is the Pairing Glue in the Cuprates? Insights from Normal and Anomalous Propagators
Tomáš Bzdušek, Richard Hlubina
Both the pairing and the pair-breaking modes lead to similar kinks of the electron dispersion curves in superconductors, and therefore the photoemission spectroscopy can not be str…
Phase diagrams of correlated electrons: systematic corrections to the mean field theory
R. Hlubina
Perturbative corrections to the mean field theory for particle-hole instabilities of interacting electron systems are computed within a scheme which is equivalent to the recently d…
First-order transition between a small-gap semiconductor and a ferromagnetic metal in the isoelectronic alloys FeSiGe
V. I. Anisimov, R. Hlubina, M. A. Korotin +4
The contrasting groundstates of isoelectronic and isostructural FeSi and FeGe can be explained within an extended local density approximation scheme (LDA+U) by an appropriate choic…
Degenerate ground state in a mesoscopic YBaCuO grain boundary Josephson junction
E. Il'ichev, M. Grajcar, R. Hlubina +8
We have measured the current-phase relationship (CPR) of symmetric 45 degree YBaCuO grain boundary Josephson junctions. Substantial deviations of the CPR from conventional tunnel-j…
Hall effect in the cuprates: the role of forward scattering on impurities
R. Hlubina
We solve the Boltzmann equation for electrons moving in a two-dimensional plane of square symmetry in the presence of a transverse magnetic field. We assume that there are two sour…
