Advantages of using YBCO-Nanowire-YBCO heterostructures in the search for Majorana Fermions

摘要

We propose an alternative platform to observe Majorana bound states in solidstate systems. High critical temperature cuprate superconductors can inducesuperconductivity, by proximity effect, in quasi one dimensional nanowires withstrong spin orbit coupling. They favor a wider and more robust range ofconditions to stabilize Majorana fermions due to the large gap values, andoffer novel functionalities in the design of the experiments determined bydifferent dispersion for Andreev bound states as a function of the phasedifference.
