  • Godoy, S; García-Colin, LS (1999)
    Mesoscopic diffusion in the ballistic regime has long been recognized to be described by the non-local Landauer diffusion coefficient: D = cLT/(2R). This is an incoherent result because, in its derivation, the quantum ...
  • Godoy, S; Micenmacher, V; García-Colin, LS (1999)
    The exact expression of the one-dimensional Boltzmann multiple-scattering coefficients, for the passage of particles through a slab of a given material, is obtained in terms of the single-scattering cross section of the ...
  • Godoy, S; Olivares-Robles, MA; García-Colin, LS (1998)
    Recent work has indicated that a telegrapher's type equation may accurately describe the diffusion of photons in highly turbid media, specially during the ballistic regime of the process. On the other hand, calculations ...
  • Godoy, S; García-Colin, LS (1998)
    We use both classical and quantum S-matrix theories to derive expressions for the ballistic diffusion current of a 1D mesoscopic crystalline solid. For both theories, we get the same local Fick's law, thus proving that ...
