Topological materials usually need to satisfy a specific property, for example they may require the materials to be nonmagnetic. This project aims to relax this requirement and to instead apply topology to materials that have a finite magnetization, which vanishes on average.
Such a generalization will enable the researchers to identify new types topological materials, and improve the control and understanding of quantum matter.
The researchers have also discovered a new way to probe and characterize Majorana particles in presence of disorder by measuring conductance through the device.
Unlike the previously used probes this method allows to verify that the Majorana particles are protected by topology, and to evaluate the quality of this protection.
