Orbital Kondo effect in a parallel double quantum dot
Zhi-qiang Bao, Ai-Min Guo, Qing-feng Sun
We construct a theoretical model to study the orbital Kondo effect in a parallel double quantum dot (DQD). Recently, pseudospin-resolved transport spectroscopy of the orbital Kondo…
Delocalization and scaling properties of low-dimensional quasiperiodic systems
Ai-Min Guo, X. C. Xie, Qing-feng Sun
In this paper, we explore the localization transition and the scaling properties of both quasi-one-dimensional and two-dimensional quasiperiodic systems, which are constituted from…
Enhanced spin-polarized transport through DNA double helix by gate voltage
Ai-Min Guo, Qing-feng Sun
We report on a way to manipulate the spin transport through double-stranded DNA contacted by normal-metal electrodes. On the basis of an effective model Hamiltonian, the conductanc…
Contact effects in spin transport along double-helical molecules
Ai-Min Guo, E. Díaz, C. Gaul +4
We report on spin transport along double-helical molecular systems by considering various contact configurations and asymmetries between the two helical strands in the regime of co…
