Abstract | We propose to realize two-dimensional superstructures of chiral topological superconductors based on marginally twisted bilayers of transition metal dichalcogenides in proximity to a conventional s-wave super-conductor. Majorana fermions arise at the domain boundaries of the AB and A'B' stacking domains as a result of a sign flip across the domain wall in a Rashba spin-orbit coupling coefficient at the valence band edge. Unlike previous models that only allow for one Majorana per boundary, each domain wall can host two helical Majorana edge states with the same Majorana polarization, preventing hybridization. This offers a promising alternative platform for studying Majorana physics. |
