2D superconductivity with strong spin-orbit interaction
We consider superconductivity confined at a two-dimensional interface with a strong surface spin-orbit (Rashba) interaction. Some peculiar properties of this system are investigated. In particular, we show that an in-plane Zeeman field can induce a supercurrent flow. PACS numbers: 74.20.-z, 74.25.-q, 74.20.Rp, 73.20.-r Most superconductors have their underlying crystal structures and the normal...
متن کاملStrong tuning of Rashba spin-orbit interaction in single InAs nanowires.
A key concept in the emerging field of spintronics is the gate voltage or electric field control of spin precession via the effective magnetic field generated by the Rashba spin-orbit interaction. Here, we demonstrate the generation and tuning of electric field induced Rashba spin-orbit interaction in InAs nanowires where a strong electric field is created by either a double gate or a solid ele...
متن کاملFermionic and Majorana bound states in hybrid nanowires with non-uniform spin-orbit interaction
We study intragap bound states in the topological phase of a Rashba nanowire in the presence of a magnetic field and with non-uniform spin orbit interaction (SOI) and proximity-induced superconductivity gap. We show that fermionic bound states (FBS) can emerge inside the proximity gap. They are localized at the junction between two wire sections characterized by different directions of the SOI ...
متن کاملStrong interface-induced spin–orbit interaction in graphene on WS2
Interfacial interactions allow the electronic properties of graphene to be modified, as recently demonstrated by the appearance of satellite Dirac cones in graphene on hexagonal boron nitride substrates. Ongoing research strives to explore interfacial interactions with other materials to engineer targeted electronic properties. Here we show that with a tungsten disulfide (WS2) substrate, the st...
متن کاملSpin-Dependent E ects in Helical Molecular Systems with Rashba-Like Spin Orbit Interaction
Strong spin-selective e ects have been recently observed in both photoemission and electrical transport experiments in biomolecular systems, opening fascinating possibilities for interfacing semiconductor and biomolecular systems to create highly e cient spintronics devices. From the theoretical and experimental point of view there are strong suggestions that molecular chirality is playing a cr...
