Topological aspects of superconductivity in quantum spin-Hall systems (QSHSs)such as thin layers of three-dimensional topological insulators (3D Tis) ortwo-dimensional Tis are in the focus of current research. We examine hybridQSHS/superconductor structures in an external magnetic field and predict agapless superconducting state with protected edge modes. It originates entirelyfrom the orbital magnetic-field effect caused by the locking of the electronspin to the momentum of the superconducting condensate flow. We show that suchspin-momentum locking can generate a giant orbital g-factor of order of severalhundreds, allowing one to achieve significant spin polarization in the QSHS inthe fields well below the critical field of the superconducting material. Wepropose a three-terminal setup in which the spin-polarized edgesuperconductivity can be probed by Andreev reflection, leading to unusualtransport characteristics: a non-monotonic excess current and a zero-biasconductance splitting in the absence of the Zeeman interaction.
