A bandmixing treatment for multiband-coupled systems via nonlinear-eigenvalue scenario

“…We have found some slightlycounterintuitive evidences leading us to suppose the inclusion of SO band, as a trigger for modifications of hh spectral distribution. Indeed, the k z hh , (x) oscillations range, shows an remark that a phenomenology of this sort, have been reported before for optical transitions [20,34,41,42] and luminescence processes [46,47]. Finally, we have retrieved in panels (2-V) and (2-VI), the 4 4 ( ) KL model to compare and to remark several differences.…”

“…Thus, the SO-band effect is a robust competitor to the sub-bandmixing, leading the hh − sh interplay to disappear in opposition to what is found when κ T grows. Therefore, the inclusion of the term m s represents certain balance in the lh − sh and hh − sh interactions and we remark that a phenomenology of this sort, have been reported before for optical transitions [20,34,42,43] and luminescence processes [47,48]. Finally, we have retrieved in panels (2-V) and (2-VI), the (4 × 4) KL model to compare and to remark several differences.…”

“…As mentioned above, this approach had been used successfully for KL models with N = 2, 4 [4,5], though without the interaction effects of the sh. We claim that sub-bandmixing effects strongly modulated by such spindependent quasi-particles, could be remarkable for the development of technological nano-spintronics devices [9,19,21,42,43]. For this reason, a more detailed analysis of the sub-bandmixing consequences together with the interplay of hh-sh and lh-sh, in the extended KL model will be shown soon after.…”
