DOI: 10.1038/s41467-018-07597-w
Abstract: In conventional superconductors, electrons of opposite spins are bound into Cooper pairs. However, when the superconductor is in contact with a non-uniformly ordered ferromagnet, an exotic type of superconductivity can appear at the interface, with… read more here.

DOI: 10.1103/physrevb.104.054519
Abstract: We predict for perhaps the first time, the occurrence of odd frequency equal spin-triplet correlations at a normal metal-superconductor junction. This result is important because the existence of equal spin-triplet correlations is associated with the… read more here.

DOI: 10.1103/physrevb.96.014514
Abstract: The close interplay between superconductivity and antiferromagnetism in several quantum materials can lead to the appearance of an unusual thermodynamic state in which both orders coexist microscopically, despite their competing nature. A hallmark of this… read more here.

Abstract: We study spin-transfer torques induced by a spin-triplet supercurrent in a magnet with the superconducting proximity effect. By a perturbative approach, we show that spin-triplet correlations realize new types of torques, which are analogous to… read more here.

Abstract: Superconductivity In conventional, and in many unconventional, superconductors, the electrons that form Cooper pairs have spins pointing in opposite directions. An applied magnetic field can easily “break” such pairs—and destroy superconductivity—by aligning both spins in… read more here.
