NettetThis is known as the integer quantum Hall (IQH) effect . The IQH effect occurs when electrons enter an incompressible state, with a robust unidirectional, or “chiral,” edge state propagating along the boundary, and all other states are localized (as shown in Figure 1d). http://damtp.cam.ac.uk/user/tong/qhe.html Nettet3. mar. 2024 · The observed breakdown of the topological protection of the integer quantum Hall effect is interpreted in terms of a long-range cavity-mediated electron hopping where the anti-resonant terms of the light-matter coupling Hamiltonian develop into a finite resistivity induced by the vacuum fluctuations. april tanggal merah
