Scientists capture electrons making seemingly impossible quantum jumps

Researchers have directly observed electrons making Landau-Zener-Majorana transitions across normally forbidden energy gaps in graphene. Teams from the University of Regensburg, Philipps-Universität Marburg and Forschungszentrum Jülich used a slow-motion electron camera to track the rapid movements under intense light-generated electric fields. Some transitions occurred with 100% probability, offering new insight into quantum behavior and potentially informing future ultrafast electronics.
