Metal-non-metal transition and specific heat of Kondo insulators

We study the metal-non-metal transition in Kondo insulators such as (CexLa1_x)3 Bi4Pt3 as a function of x, magnetic field, pressure and temperature. The many body effects are treated diagonalizing the site Hamiltonian and embedding this solution into the lattice. The disorder is studied using a real...
