Manipulation of Majorana bound states in proximity to a quantum ring with Rashba coupling Medina, Fabián Gonzalo Martínez, Dunkan Díaz Fernández, Álvaro Domínguez-Adame Acosta, Francisco Rosales, Luis Orellana, Pedro A. The quest for Majorana zero modes in the laboratory is an active field of research in condensed matter physics. In this regard, there have been many theoretical proposals; however, their experimental detection remains elusive. In this article, we present a realistic setting by considering a quantum ring with Rashba spin-orbit coupling and threaded by a magnetic flux, in contact with a topological superconducting nanowire. We focus on spin-polarized persistent currents to assess the existence of Majorana zero modes. We find that the Rashba spin-orbit coupling allows for tuning the position of the zero energy crossings in the flux parameter space and has sizable effects on spin-polarized persistent currents. We believe that our results will contribute towards probing the existence of Majorana zero modes. 2023-06-22T10:40:52Z 2023-06-22T10:40:52Z 2023-06-22T10:40:52Z 2022-01-12 journal article https://hdl.handle.net/20.500.14352/71341 2045-2322 10.1038/s41598-022-05043-y eng PID2019-106820RB-C21 https://creativecommons.org/licenses/by/3.0/es/ open access Atribución 3.0 España Nature Portfolio
