Spin-orbit-coupled superconductivity | Scientific Reports.

Systems simultaneously exhibiting superconductivity and spin-orbit coupling are predicted to provide a route toward topological superconductivity and unconventional electron pairing, driving significant contemporary interest in these materials. In this article, we review the recent progress in surface atomic-layer superconductors on semiconductor substrates with Rashba/Zeeman-type spin-orbit coupling (SOC). After introduction of some of the basics of Rashba/Zeeman-type SOC and its effects on superconductivity, representative surface structures with relevant features are described in terms of their crystalline and electronic.

Effects of spin-orbit coupling on spin-fluctuation induced pairing in iron-based superconductors Daniel D. Scherer, Brian M. Andersen We perform a theoretical study of the leading pairing instabilities and the associated superconducting gap functions within the spin-fluctuation mediated pairing scenario in the presence of spin-orbit coupling (SOC).. Abstract We study theoretically the onset of nonuniform superconductivity in a one-dimensional single wire in presence of Zeeman (or exchange field) and spin-orbit coupling. Using the Green's function formalism, we show that the spin-orbit coupling stabilizes modulated superconductivity in a broad range of temperatures and Zeeman fields.

Nonuniform superconductivity in wires with strong spin-orbit coupling.

Spin-orbit-coupled ferroelectric superconductivity Abstract Motivated by recent studies on ferroelectriclike order coexisting with metallicity, we investigate ferroelectric (FE) superconductivity in which a FE-like structural phase transition occurs in the superconducting state. Superconductivity arises when solids have conducting bands (singly occupied wave functions) that do not have electron-nuclear scattering (Fermi contact) and the temperature is low... result of spin-orbit coupling at the critical transition temperature in response to an external magnetic field to drive the formation of an opposing macroscopic.

Surface atomic-layer superconductors with Rashba/Zeeman-type spin-orbit.

. The confluence of superconductivity and spin-orbit (SO) interactions in the solid-state has presented several opportunities towards fault-tolerant quantum information processing. The SO interaction, born out of the relativistic interplay between the spin and orbital degrees of motion of electrons, manifests as an effective, local magnetic. Centrosymmetric materials with spin-degenerate bands are generally considered to be trivial for spintronics and related physics. In two-dimensional (2D) materials with multiple degenerate orbitals, we find that the spin-orbit coupling can induce spin-orbital locking, generate out-of-plane Zeeman-like fields displaying opposite signs for opposing orbitals, and create novel electronic states.

Here, using density functional theory calculations, we report that the strength of the spin-orbit coupling (SOC) in NiTe 2 can be tuned by Se substitution. This results in negative shifts of the bulk Dirac point (BDP) while preserving the type-II Dirac band. Indeed, combined studies using scanning tunneling spectroscopy and angle-resolved.

Spin-orbit coupling enhanced superconductivity in Bi-rich compounds.

We have grown few unit cells of epitaxial LaAlO3 (LAO) on TiO2 terminated SrTiO3 (STO) substrates using oxide MBE technique, which shows an interface superconductivity below about 0.3 K. By fabricating a back gate electrode via the STO substrate, the superconductor-to-insulator transition was observed by applying gate voltages on a macroscopic size of the two-dimensional electron liquid (2DEL...

Ultrathin two-dimensional superconductivity with strong.

.. Superconductivity and spin-orbit (SO) interaction have been two separate emerging fields until very recently that the correlation between them seemed to be observed. However, previous experiments concerning SO coupling are performed far beyond the superconducting state and thus a direct demonstration of how SO coupling affects superconductivity remains elusive.

Superconducting devices with spin-orbit coupling. Electron spin flip scattering within materials leads to energy dissipation and ultimately this irreversible process limits the operating efficiency of devices based on spin-electronics (spintronics). Dissipationless spin currents can be generated by the quantum hall effect in material systems in.

Controlling Spin-Orbit Coupling to Tailor Type-II Dirac Bands.

In quantum physics, the spin-orbit interaction (also called spin-orbit effect or spin-orbit coupling) is a relativistic interaction of a particle's spin with its motion inside a potential.A key example of this phenomenon is the spin-orbit interaction leading to shifts in an electron's atomic energy levels, due to electromagnetic interaction between the electron's magnetic dipole, its. Spin-orbit coupling in systems that lack inversion symmetry. Chapter 1 gives an in-troduction to the context of spin-orbit coupling in condensed matter physics and the role of inversion symmetry breaking. The remainder of the thesis is divided into two parts. Part 1 explores the e ects of spin-orbit coupling on low-energy electron-impurity.
