Ion acceleration driven by superintense laser pulses is attracting an impressive and steadily
increasing effort. Motivations can be found in the applicative potential and in the perspective …

Fe-based superconductors bridge a gap between MgB 2 and the cuprate high temperature
superconductors as they exhibit multiband character and transition temperatures up to …

The discovery of new high-temperature superconductors based on FeAs has led to a new
'gold rush'in high-TC superconductivity. All of the new superconductors share the same …

The parton distribution function for ab quark in the B meson (called the shape function) plays
an important role in the analysis of the B→ X s γ and B→ X u ℓ ν¯ data, and gives one of the …

An overview of the recent development of the superconducting FeSe1− x and related
compounds is presented. Methods to synthesize high purity polycrystalline samples, single …

The electronic and magnetic properties of the excess Fe in iron telluride Fe (1+ x) Te are
studied by density functional calculations. We find that the excess Fe occurs with valence …

We investigated the temperature dependence of the upper critical fields H c 2 (T) of a
superconducting FeTe 0.6 Se 0.4 single crystal by measuring its resistivity in static magnetic …

Iron selenide (FeSe x) crystals with lateral dimensions up to millimeters were grown via a
vapor self-transport method. The crystals consist of the dominant α-phase with trace …

We have investigated the high-pressure crystal and electronic structures of superconducting
FeSe by high-resolution synchrotron powder X-ray diffraction and density functional theory …

Tetragonal iron selenide, FeSe, the layered parent compound of the recently discovered
superconducting arsenide family, has previously been shown to be non-magnetic and …
