Magnonic superconductivity

Science Advances
We uncover a superconducting state with partial spin polarization induced by a magnetic field. This state, which we call “magnonic superconductor,” lacks a conventional pairing order parameter but is characterized instead by a composite order parameter that represents the binding of electron pairs and magnons. We rigorously demonstrate the

Superconductivity in pressurized CeRhGe3 and related non-centrosymmetric compounds

, 2017
We report the discovery of superconductivity in pressurized CeRhGe3, until now the only remaining non-superconducting member of the isostructural family of non-centrosymmetric heavy-fermion compounds CeTX3 (T = Co, Rh, Ir and X = Si, Ge ...

Emergent Higgsless Superconductivity [PDF]

, 2017
We present a new Higgsless model of superconductivity, inspired from anyon superconductivity but P- and T-invariant and generalizable to any dimension. While the original anyon superconductivity mechanism was based on incompressible quantum Hall fluids ...

T * -phase superconductivity [PDF]

Physica C: Superconductivity and its Applications, 1989
Abstract The T ⋆ -phase is a mixed rare earth oxide phase forming at the composition R 2 CuO 4 . Its crystal structure is intermediate between the La 2 CuO 4 and Nd 2 CuO 4 structures. Sr-doped samples have T c onsets as high as 37 K. We discuss the systematics of T c of T ⋆ -phases as a function of Sr doping, rare earth mixture and oxygenation ...

Control of tetrahedral coordination and superconductivity in FeSe0.5Te0.5 thin films

, 2010
We demonstrate a close relationship between superconductivity and the dimensions of the Fe-Se(Te) tetrahedron in FeSe0.5Te0.5. This is done by exploiting thin film epitaxy, which provides controlled biaxial stress, both compressive and tensile, to ...

Superconductivity and localization [PDF]

Physics Reports, 1997
We present a review of theoretical and experimental works on the problem of mutual interplay of Anderson localization and superconductivity in strongly disordered systems. We start with brief discussion of modern aspects of localization theory including the basic concept of scaling, self-consistent theory and interaction effects.

Superconductivity up to 30 K in the vicinity of quantum critical point in BaFe$_{2}$(As$_{1-x}$P$_{x}$)$_{2}$

, 2009
We report bulk superconductivity induced by an isovalent doping of phosphorus in BaFe$_{2}$(As$_{1-x}$P$_{x}$)$_{2}$. The P-for-As substitution results in shrinkage of lattice, especially for the FeAs block layers. The resistivity anomaly associated with

Superconductivity at 93 K in a new mixed-phase Yb-Ba-Cu-O compound system at ambient pressure.

Physical Review Letters, 1987
A stable and reproducible superconductivity transition between 80 and 93 K has been unambiguously observed both resistively and magnetically in a new Y-Ba-Cu-O compound system at ambient pressure.
