Quantum Transport in Open Billiards: Dependence on Degree of Opening
スポンサーリンク
概要
- 論文の詳細を見る
Quantum transport is studied for open billiards with a pair of conducting leads.Boundaries of the billiards are of squared-cosine shape and the electric conductanceas a function of the Fermi wave number is computed by tuning the degree of opening.A quantized plateau accompanied by a sequence of intermittent sharp dips ina 'strongly opened' case changes into anomalously noisy fltmctuations in a 'weaklyopened' case. In the latter case, however, the smoothed conductance shows regularoscillations around some plateau values. l'he failure of the adiabatic approximationis also discussed.quantum transport, open billiard, degr<:e of opening, conductance fltuctuation
