Nematic electronic order is rare and its onset often indicates a phase transition. Here, Li et al. report a nematic superconducting state in Ba0.5K0.5Fe2As2 by measuring the angular dependence of the in-plane and out-of-plane magnetoresistivity.

A new procedure is proposed to optimize the intercarrier spacing and wavelength selective switch (WSS) bandwidth for superchannels, using a Monte Carlo simulation. We perform an exhaustive assessment of the optical signal-to-noise ratio (OSNR) penalt

Nematic order often breaks the tetragonal symmetry of iron-based superconductors. It arises from regular structural transition or electronic instability in the normal phase. Here, we report the observation of a nematic superconducting state, by measu

Allotropes of carbon are promising materials for the next generation of electronics. In particular, boron-doped synthetic diamond, which is typically highly disordered, provides a powerful stage for studying superconductivity in a three-dimensional g

The determination of the pairing symmetry is one of the most crucial issues for the iron-based superconductors, for which various scenarios are discussed controversially. Non-magnetic impurity substitution is one of the most promising approaches to a

This paper develops a dynamic model for the timing and terms of mergers and acquisitions. In contrast to other models, we show that firms agree about the timing independently from how the merger surplus is shared. Firms agree on the timing and discus

Using two experimental techniques, we studied single crystals of the 122-FeAs family with almost the same critical temperature, Tc. We investigated the temperature dependence of the lower critical field of a single crystal under static magnetic field

Given the global financial crisis and, particularly, the European sovereign-debt crisis, European countries have the urgent need to promote output growth. However, due to the current financial constraints, it is difficult for the Governments to stimu
