Description :
We present an atomic resolution scanning tunneling spectroscopy study of superconducting
BaFe1.8Co0.2As2 single crystals in magnetic fields up to 9 T. At zero field, a single gap with coherence
peaks at [untranscribable character] = 6:25 meV is observed in the densit...

Description :
The static spin susceptibility, χsSQ and χsNMR, in C60 superconductors K3C60 and Rb3C60 was studied using a dc superconducting quantum interference device magnetometer and 13C NMR. We found that χsSQ has a peculiar temperature (T) dependence behaving as (1-CT2) with a positive constant C∼(1×10-6) de...

Description :
Magnetic, transport, thermal, and crystallographic properties are reported for single crystals of CeRhSn crystallizing in the hexagonal ZrNiAl-type structure. We found high anisotropy in both electrical resistivity (ρ a≈5ρc at 70 K) and magnetic susceptibility (X c≈10Xa at 0.4 K), which is atypical ...

Description :
The unconventional superconductivity in the newly discovered iron-based superconductors is intimately related to its multiband/multiorbital nature. Here we report the comprehensive orbital characters of the low-energy three-dimensional electronic structure in BaFe_<1.85>Co_<0.15>As_2 by studying the...

Description :
A stochastic background of gravitational waves is expected to arise from a superposition of many incoherent sources of gravitational waves, of either cosmological or astrophysical origin. This background is a target for the current generation of ground-based detectors. In this article we present the...

Description :
We present the results of a weakly modeled burst search for gravitational waves from mergers of nonspinning intermediate mass black holes in the total mass range 100-450 M-circle dot and with the component mass ratios between 1: and 4:1. The search was conducted on data collected by the LIGO and Vir...
