We report the discovery of superconductivity on the border of long-range magnetic order in the itinerant-electron helimagnet MnP via the application of high pressure. Superconductivity with T(sc)≈1  K emerges and exists merely near the critical pressure P(c)≈8  GPa, where the long-range magnetic order just vanishes. The present finding makes MnP the first Mn-based superconductor. The close prox...

Abstract Generation and detection of spinful Cooper pairs in conventional superconductors has been intensely pursued by designing increasingly complex magnet-superconductor hybrids. Here, we demonstrate theoretically that magnons with nonzero wavenumbers universally induce a cloud triplet around them an adjacent superconductor. The resulting composite quasiparticle, termed magnon-cooparon, cons...

Abstract We consider a bilayer system with conventional s-wave superconductor and chiral helimagnet. If we assume that structure of an external magnetic field from the helimagnet is same as moment in helimagnet, helical applied to superconductor. Our previous simulation showed vortex structures depend on strongly well amplitude field. study how pitch affects transition temperature. For this pur...

We explore the effects of an applied strong external magnetic field in the structure and magnitude of the color superconducting diquark condensate of a three massless flavor theory. The long-range component of the B field that penetrates the superconductor enhances the condensates formed by quarks charged with respect to this electromagnetic field.

We present simulations of the dynamic critical state for a 2D superconductor with strong pinning centers, corresponding to a matching field twice the applied magnetic field. The sharp crossover between the plastic regime, at low current density and temperature, and the fluid flow regime for flux motion is characterized by the activation energy for flux motion and the transverse diffusion of the...

In this paper, the noise equivalent power (NEP) of an optical sensor based ongraphene-superconductor junctions in the constant current mode of operation has beencalculated. Furthermore, the necessary investigations to optimize the device noise withrespect to various parameters such as the operating temperature, magnetic field, deviceresistance, voltage and current bias have been presented. By s...
