WebApr 13, 2024 · This leads to a characteristic temperature dependence of the oscillation frequency which is a strong indicator of nontrivial topology, even for multi-band metals with complex Fermi surfaces....
WebFrom Fermi-Dirac statistics, however, we find that average energies are on the order of the Fermi energy, which are typically about 5 eV. So the classical prediction is wrong by about two orders of magnitude. The difference is due to the fact that electrons obey the exclusion principle, and cannot all fit in the low-lying states near kT.
