Advantages of using high-temperature cuprate superconductor heterostructures in the search for Majorana fermions

We propose an alternative platform to observe Majorana bound states in solid-state systems. High-critical-temperature cuprate superconductors can induce superconductivity, by the proximity effect, in quasi-one-dimensional nanowires with strong spin-orbit coupling. They favor a wider and more robust range of conditions to stabilize Majorana fermions due to the large gap values, and offer novel functionalities in the design of the experiments determined by different dispersion for Andreev bound states as a function of the phase difference.
