Description
A detailed examination of the plateau transition in the quantum Hall effect reveals the presence of axion influence. In quantum Hall effect experiments, strong magnetic fields are used, and microwaves generated by axions from the surrounding metallic walls are emitted. These microwaves are absorbed by localized electrons, causing them to transition to a delocalized state and contribute to the current. This effect impacts the Hall conductivity. When the Fermi energy is in the localized state of electrons, the Hall conductivity remains constant, forming a plateau. However, when the electrons are in the delocalized state, the Hall conductivity changes, leading to a plateau transition. The presence of axion-induced microwaves affects this plateau transition. Therefore, by carefully re-examining the plateau transition, we can observe the axion’s influence and demonstrate that its mass is 10^{-5} eV
