TLDR
A flop transition in the spin density wave order parameter vector is proposed, which affects the nature of the superconducting state and leads to the appearance of several new phases.Abstract:
We discuss the possibility of the coexistence of spin density waves (antiferromagnetism) and triplet superconductivity as a particular example of a broad class of systems where the interplay of magnetism and superconductivity is important. We focus on the case of quasi-one-dimensional metals, where it is known that antiferromagnetism is in close proximity to triplet superconductivity in the pressure versus temperature phase diagram. Over a range of pressures, we propose an intermediate nonuniform phase consisting of antiferromagnetic and triplet superconducting orders. In the coexistence region, we propose a flop transition in the spin density wave order parameter vector, which affects the nature of the superconducting state and leads to the appearance of several new phases.read more

Superconductivity in a layered perovskite without copper

TL;DR: In this article, it was shown that the presence of copper is not a prerequisite for the existence of superconductivity in a layered perovskite, and that the low value of the superconducting transition temperature (Tc = 0.93 K) points towards a special role for copper in the high-temperature superconductors.
