1 Mattis, Daniel C.Electron states in random alloys with short-range orderWe present an accurate and economical iterative method of calculating the energy levels of a disordered or partly ordered random alloy. Results presented for one- and three-dimensional simple cubic lattices compare favorably with exact calculations. We also present the systematic effects of partia...Random alloys; Density of state1977-04
2 Mattis, Daniel C.Ratio 2Δ0/kTc in superconductivityIn high-temperature superconductors, values of the ratio R-2Δ0/kTc have been reported in the range 2-10, whereas low-temperature superconductors rarely deviate by as much as 50% from the BCS prediction R =3.54. Could this variability relate to the density of states near the Fermi surface? Our calcu...Density of state; Superconductors1991-12
3 Mattis, Daniel C.Second-order phase transition in a model random alloyWe investigate the existence and stability of long-range order in a simple model of a binary alloy. We find that for electron concentrations in the vicinity of one per atom, in bipartite lattices, long-range order of the atoms exists at low temperatures, and we find that the system undergoes a secon...Phase transition; Random alloys; Quasiparticles; Density of state1973-03
4 Mattis, Daniel C.Short-range versus long-range order in a model binary alloyWe calculate the free energy of a linear binary metallic alloy using an exact transfer-matrix formalism. We obtain for the first time the electronic band structure when there is nonvanishing short-range order and calculate the temperature dependence of the short-range order parameter. Following Foo...Binary alloys; Density of state; Free energy1971-07
