Majorana bound states can appear quite naturally in superconductors. But, how can we find the Marjoranas? Michael will explain more about that in this video.

Main takeaways

• Particle-hole symmetry is fundamental to Majoranas. For a particle at energy E must have an antiparticle(hole) at energy –E.
• At zero energy, we then get immediately Majorana Bounds states. We thus have to look for superconductors with zero energy.
• Quantum mechanical zero-point motion makes it difficult to find states with zero energy in conventional superconductors.
• Experimentalists attempt to engineer a nontrivial superconductor out of ordinary materials to find Majoranas.
