  • Exact propagator of a two dimensional system 
    Udom Robkob (Chulalongkorn University, 1987)
    The propagator for an electron moving in a two-dimensional system under the influence of a transverse magnetic field B, a time varying external force field f(s) and a nonlocal harmonic force, is evaluated exactly by ...
  • Feynman path integration of elelectron transport in two dimensions 
    Udom Robkob (Chulalongkorn University, 1996)
    We have studied the formulation of quantum transport problem in the form of Feynman's path integrals. The idea was originated from the study of polaron transportation by Thornber. We have applied this technique to the ...
