Recently, we showed that the self-field transport critical current, Ic(sf), of a superconducting wire can be defined in a more fundamental way than the conventional (and arbitrary) electric field criterion, Ec = 1 microV/cm. We defined Ic(sf) as the

Physical Review B

In cuprates, a precursor state of superconductivity is speculated to exist above the critical temperature ${\mathrm{T}}_{\mathrm{C}}$. Here we show via a combination of far-infrared ellipsometry and ultrafast broadband optical spectroscopy that signa

Pseudogap inYBa2Cu3O6+δis not bounded by a line of phase transitions: Thermodynamic evidence

Autor: Ivan Kokanović, James Storey, John Loram, J. L. Tallon, J. R. Cooper

Publikováno v: Physical Review B. 89

We discuss a recent resonant ultrasound spectroscopy (RUS) study of YBa_2Cu_3O_6+δ, which infers a line of phase transitions bounding the pseudogap phase and argue that this scenario is not supported by thermodynamic evidence. We show that the anoma
