We study spin-polarized quasiparticle transport in a mesoscopic superconductor with a spin-splitting field in
the presence of coflowing supercurrent. In such a system, the nonequilibrium state is characterized by charge,
spin, energy, and spin-energy modes. Here we show that in the presence of both spin splitting and supercurrent,
all these modes are mutually coupled. As a result, the supercurrent can convert charge imbalance, which in the
presence of spin splitting decays on a relatively short scale, to a long-range spin accumulation decaying only via
inelastic scattering. This effect enables coherent charge-spin conversion controllable by a magnetic flux, and it
can be detected by studying different symmetry components of the nonlocal conductance signal.

Charge transport through spin-polarized tunnel junction between two spin-split superconductors
Rouco, Mikel; Chakraborty, Subrata; Aikebaier, Faluke; Golovach, Vitaly N.; Strambini, Elia; Moodera, Jagadeesh S.; Giazotto, Francesco; Heikkilä, Tero T.; Bergeret, F. Sebastian (American Physical Society, 2019)We investigate transport properties of junctions between two spin-split superconductors linked by a spin-polarized tunneling barrier. The spin-splitting fields in the superconductors (S) are induced by adjacent ferromagnetic ... -
Current Rectification in Junctions with Spin-Split Superconductors
Ilić, Stefan; Virtanen, Pauli; Heikkilä, Tero T.; Bergeret, F. Sebastián (American Physical Society (APS), 2022)Spin-split superconductors exhibit an electron-hole asymmetric spin-resolved density of states, but the symmetry is restored upon averaging over spin. On the other hand, asymmetry appears again in tunneling junctions of ... -
Spin torques and magnetic texture dynamics driven by the supercurrent in superconductor/ferromagnet structures
Bobkova, I. V.; Bobkov, A. M.; Silaev, Mikhail (American Physical Society, 2018)We introduce the general formalism to describe spin torques induced by the supercurrents injected from the adjacent superconducting electrodes into the spin-textured ferromagnets. By considering the adiabatic limit for the ... -
Microwave photoassisted dissipation and supercurrent of a phase-biased graphene-superconductor ring
Dou, Ziwei; Wakamura, Taro; Virtanen, Pauli; Wu, Nian-Jheng; Deblock, Richard; Autier-Laurent, Sandrine; Watanabe, Kenji; Taniguchi, Takashi; Guéron, Sophie; Bouchiat, Hélène; Ferrier, Meydi (American Physical Society (APS), 2021)Irradiating normal-superconducting junctions with microwave photons produce spectacular effects, such as Shapiro steps and photoinduced modifications of the dc supercurrent. Moreover, microwave irradiation can also have ... -
Stimulated quasiparticles in spin-split superconductors
Virtanen, Pauli; Heikkilä, Tero; Bergeret, F. S. (American Physical Society, 2016)In superconductors spin split by an exchange field, thermal effects are coupled to spin transport. We show how an oscillating electromagnetic field in such systems creates spin imbalance, that can be detected with a ...
