Webshould obey the equipartition theorem. At room temperature of 300 K, the average energy would then be E = 3 2 kT = 3 2 (8.61 ×10−5 eV/K)(300 K) = 0.039 eV. From 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 ...

Webcheck for any analogs of the LL theorem in these systems. Furthermore, the authors of some theoretical articles (see e.g. [18]) claim that violation of this condition rules out the possibility of creating a quasiparticle pattern of phe-nomena in strongly correlated Fermi systems. However, as we will see, this is not the case: the quasiparticle pic- In number theory, Fermat's Last Theorem (sometimes called Fermat's conjecture, especially in older texts) states that no three positive integers a, b, and c satisfy the equation a + b = c for any integer value of n greater than 2.
