AI Article Synopsis
- * A twist angle near 45° may enable the high-T_{c} superconductor to function as a fully gapped topological superconductor, potentially maintaining functionality at temperatures close to its critical temperature of approximately 90 K.
- * These Majorana zero modes might remain stable at high temperatures and could exhibit greater protection from interface-related issues compared to other systems being studied for similar properties.
Article Abstract
We employ analytical and numerical approaches to show that unpaired Majorana zero modes can occur in cores of Abrikosov vortices at the interface between a three-dimensional topological insulator, such as Bi_{2}Se_{3}, and a twisted bilayer of high-T_{c} cuprate superconductor, such as Bi_{2}Sr_{2}CaCu_{2}O_{8+δ}. When the twist angle is close to 45° the latter has been predicted to form a fully gapped topological superconductor up to temperatures approaching its native T_{c}≃90 K. Majorana zero modes in these structures will persist up to unprecedented high temperatures and, depending on the quality of the interface, may be protected by gaps with larger magnitudes than other candidate systems.
