Popular Summary Most everyday materials obey Ohm’s law, which says the current through a material is proportional to the voltage across it. In topological materials, violations of this law can be related to the underlying physics of the material. Much experimental and theoretical work in this area has focused on studying current that does not vary in space across the material.
