             abstract = "A self-consistent many-body theory of disordered systems, decribed 
                         by the Hubbard Hamiltonian with random transfer integrals, has 
                         been developed in the presence of a magnetic field and impurity 
                         correlation, incorporated through a hard core pair correlation 
                         function. The low temperature electronic specific heat and the 
                         zero temperature susceptibility of uncompensated P doped Si have 
                         been calculated as a function of impurity concentration and 
                         compared with experimental data. It is found that for the upper 
                         Hubbard band centeredat the corresponding value of D the specific 
                         heat agrees wel lwith experiment in the entire 
                         semiconductor-to-dilute-metallic region. Both the electron and 
                         impurity correlation enhance the susceptibility and quench the 
                         specific heat. The behavior of the relative change in the specific 
                         heat due to the magnetic field agrees qualitatively with the low 
                         temperature experimental results.",
