Formation of Fabry-Perot resonances in double-barrier chaotic billiards

摘要: We study wave transport through a chaotic quantum billiard attached to two waveguides via barriers of arbitrary transparencies in the semiclassical limit large number open scattering channels. focus attention on ergodic regime, which is described by using random-matrix approach resonance together with an extended version Nazarov's circuit theory. By varying relative strength barriers' reorganization relevant resonances energy interval where takes place leads full suppression high transmission modes. provide detailed quantitative description process means both numerical and analytical evaluations average density eigenvalues. show that Fabry-Perot modes can be used as kind order parameter for this transition. A diagram presented function exhibiting regimes transition lines.
