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

Abstract

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 properties. This is followed by recent experimental studies that have revealed anomalous superconducting phenomena, which can be attributed to the effects of Rashba/Zeeman-type SOC. Future prospects, likely to be driven by instrumentational developments, are given as a concluding remark.

Tuning the spin texture of graphene with size-specific Cu n clusters: a first-principles study

“…In the case of Cu 3 , we observe a complete out-of-plane polarization, with negligible in-plane spin component. The observed spin texture indicates a dominant Zeeman SOC term, originating from the lack of in-plane inversion symmetry and the presence of a local magnetic moment [55]. A small Rashba SOC is also present, due to the symmetry reduction in the out-of-plane direction.…”

Ternary superconducting hydrides stabilized via Th and Ce elements at mild pressures

“…Since the discovery of the superconductivity of mercury in 1911 [1] , searching for room-temperature superconductors is an ultimate goal in condensed matter physics and materials science. Within 110 years of exploration, researchers discovered many high critical temperature ( T c ) superconductors [2] , [3] , [4] , [5] , [6] , such as cuprate, iron-based, interface, and organic superconductors. The highest T c of 164 K was achieved in Hg-Ba-Ca-Cu-O [7] through diamond anvil cell (DAC) compression to 31 GPa, but the T c value remains lower than room temperature.…”

Comparison of Lumped Oscillator Model and Energy Participation Ratio Methods in Designing Two-Dimensional Superconducting Quantum Chips

“…Superconducting qubits stand out among many schemes due to their strong designability, ample controllable space, high scalability, and high compatibility with existing micro-nano processing technologies [ 5 , 6 , 7 ]. The study of superconductivity itself is of fundamental importance [ 8 , 9 ]. Moreover, it is also important in quantum computing, like realizing quantum gates [ 10 , 11 ], and quantum mechanical sensing [ 12 ].…”
