摘要: A class of unitary transformations reflective character is proposed for multi-mode quantum transport systems. The simplest these discussed in detail. To optimise the transformation parameters, a new variational principle introduced which based on definition positive definite 'measure non-diagonality' each state. optimised removes leading order non-diagonality phonon coupling strength D (from D0 to D-2 D2>>1 and from D2 D4 D2<<1). In this manner basic shortcoming diffusion systems, dominating between energetically far-off states, drastically reduced.
