Interpolation formula for propagators in systems with intermediate degree of transport coherence

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

We present an interpolation formula for the probability propagators of the generalized master equation appropriate for the description of the motion of quasiparticles in systems with an intermediate degree of transport coherence. Although highly simplified in form, the formula is convenient for practical computations on complex systems whose exact dynamics would be essentially impossible to obtain. The formula has features analogous to some in the relaxation time prescription for the calculation of the Boltzmann distribution function. We point out the manner in which the interpolation formula may be used in conjuction with experimental data as well as with model calculations.
