⚛️ Majorana current driven by charge flow in magnet/graphene
Researchers have investigated the Majorana current generated when a charge current flows through Kitaev magnet/graphene bilayers. This study specifically focused on how Majorana fermions within the Kitaev magnet are moved by electrons present in graphene. The team calculated the Majorana current density using a perturbation based on Kondo-type Majorana-electron coupling. This result provides an analytical expression showing electronic control over charge-neutral Majorana fermions. Furthermore, the paper discusses the Majorana heat current induced by charge current and estimates their respective magnitudes.
