Physical mechanisms for zero-bias conductance peaks in Majorana nanowires
Haining Pan, S. Das Sarma
Abstract
The authors describe the different mechanisms leading to zero-bias conductance peaks in Majorana nanowires. They conclude that the experimentally observed zero-bias peaks most likely arise from strong disorder in the system and are therefore not topological. The implication is that disorder in nanowires must be suppressed in order for topological Majorana modes to emerge.
