[2201.06265] Spin-orbit-coupled superconductivity with spin.

Significance. By studying epitaxially grown Pb thin films, this paper explores a new regime in the physics of uniform 2D superconductivity, in which the spin–orbit coupling-induced Rashba splitting is larger than the superconducting gap. The first quantitative determination of superfluid rigidity in nearly atomically thin 2D superconductors.

Superconductivity in crystals with spin-orbit coupling.

Described by spin-orbit coupling in the normal state and thus must be related to superconductivity. Such results are reminiscent of the intriguing influence of disorder on superconductivity27–33. The superconducting transition temperature T c of the SrTiO3/LaAlO3 interface was varied by the electric field effect. The anisotropy of the upper critical field and the normal-state magnetotransport were studied as a function of gate voltage. The spin-orbit coupling energy ϵSO is extracted.

Ultrathin two-dimensional superconductivity with strong.

The interplay between superconductivity and spin-orbit coupling (SOC) is at the centre of intensive research efforts as it can generate a variety of unique phenomena such as the occurrence of triplet superconductivity, for instance 1.Recently, hybrid nanostructures involving a superconductor in proximity to a semiconducting nanowire with a strong SOC have been proposed as an ideal system to. As a result of this spin-orbit-parity coupling (SOPC): (i) there is a first-order superconductor-metal transition at B c 2 that is much higher than the Pauli paramagnetic limit B p, (ii) spin-susceptibility is anisotropic with respect to in-plane directions and can result in possible anisotropic B c 2, and (iii) the B c 2 exhibits a strong gate.

Antisymmetric form of spin–orbit coupling that admits both spin-singlet and spin-triplet components of the superconducting wavefunction.

We investigate the. Systems simultaneously exhibiting superconductivity and spin–orbit coupling are predicted to provide a route toward topological superconductivity and unconventional electron pairing, driving. Recently, materials with strong spin-orbit coupling (SOC) effect have attracted a great deal of attention due to the resulted novel topological phases.

Ising and spin orders in the iron-based superconductors (0).

Antiferromagnetism is relevant to high-temperature (high-Tc) superconductivity because copper oxide and iron arsenide superconductors arise from electron- or hole-doping of their antiferromagnetic parent compounds1-6. There are two broad classes of explanation for antiferromagnetism: in the 'local moment ' picture, appropriate for the. Spin-orbit coupling and superconductivity spin-orbit coupling as a perturbation spin singlet pairing: minor effect spin triplet pairing: allmost all pairing states severely suppressed weakly affected pairing states: CePt 3Si: k x k y. The Superconducting Phase and the Magnetic Field.

Model of superconductivity the energy gap that is known to appear in superconducting states is caused by spin-orbit coupling and the magnetic field associated with the superconducting state. The magnetic field dependence of the energy gap in this model should be linear. In the. Spin-orbit-coupled superconductivity with spin-singlet non-unitary pairing. An unconventional superconductor is distinguished with two types of gap functions: unitary and non-unitary. This core subject has been concentrated on purely spin-triplet or singlet-triplet mixed superconductors. However, the generalization to a purely spin-singlet. In non-centrosymmetric superconductors, where the crystal structure lacks a centre of inversion, parity is no longer a good quantum number and an electronic antisymmetric spin-orbit coupling (ASOC) is allowed to exist by symmetry. If this ASOC is sufficiently large, it has profound consequences on the superconducting state.

Superconductivity in the presence of spin-orbit interactions.

Overview of topological superconductivity will be given. 1.1. Conceptual description of key results in non-centrosymmetric superconductivity The key microscopic ingredient in understanding the physics of superconductors without inversion symmetry is the anti-symmetric spin–orbit coupling (ASOC) of the single electron states in a material. As a result of this spin-orbit-parity coupling (SOPC): (i) there is a first-order superconductor-metal transition at B_{c2} that is much higher than the Pauli paramagnetic limit B_{p}, (ii) spin-susceptibility is anisotropic with respect to in-plane directions and can result in possible anisotropic B_{c2}, and (iii) the B_{c2} exhibits a strong.

Superconductivity in large spin-orbit coupled material IrTe2.

The electron Bloch states in crystals with spin-orbit coupling do not always transform under symmetry operations in the same way as the pure spin-1/2 states. This has profound consequences for the gap symmetry and nodal structure of superconductors.

Tuning Ising superconductivity with layer and spinâ€“orbit.

The confluence of superconductivity and spin–orbit (SO) interactions in the solid-state has presented several opportunities towards fault-tolerant quantum information processing.

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.

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. Recent theories and experiments have shown that spin triplet Cooper pairs will also appear in a uniform magnetic structure S/F system with spin-orbit coupling (SOC) [25-28]. By introducing a heavy metal (HM) layer, SOC can be induced in the S/HM interface in the F/S/HM heterostructure.
