Heavy fermion semiconductors pdf

Symplectic large-N theory of topological heavy-fermion semiconductors. Maxim Dzero. Department of Physics, Kent State University, Kent, filexlib. The heavy-fermion semiconductors are described by the Anderson lattice in the mean-field slave boson approximation. As the number of electrons is varied by Among the low-temperature ground states observed in heavy fermion compounds are exotic superconductors and magnets, as well as unusual semiconductors.
T = 0 K, but become heavy-fermion metals with increasing temperature. They are called the Kondo insulators. Second [3], several metallic systems exhibit The heavy fermion semiconductors, or Kondo insulators, are very narrow gap semiconductors in which the properties show unusual temperature dependencies.
