Extrinsic and intrinsic ratchet response of a quantum dissipative spin-orbit medium
Sergey Smirnov, Dario Bercioux, Milena Grifoni +1
Traditionally the charge ratchet effect is considered as a consequence of the extrinsic spatial asymmetry engineered by external asymmetric periodic potentials. Here we demonstrate…
Electronic spectra of commensurate and incommensurate DWNTs in parallel magnetic field
Magdalena Marganska, Shidong Wang, Milena Grifoni
We study the electronic spectra of commensurate and incommensurate double-wall carbon nanotubes (DWNTs) of finite length. The coupling between nanotube shells is taken into account…
Interplay between quantum dissipation and an in-plane magnetic field in the spin ratchet effect
Sergey Smirnov, Dario Bercioux, Milena Grifoni +1
We investigate the existence of the pure spin ratchet effect in a dissipative quasi-one-dimensional system with Rashba spin-orbit interaction. The system is additionally placed int…
Linear conductance of an interacting carbon nanotube ring
M. Eroms, L. Mayrhofer, M. Grifoni
Linear transport through a single-walled carbon nanotube ring (CNR), pierced by a magnetic field and capacitively coupled to a gate voltage source, is investigated starting from a…
The spectrum of interacting metallic carbon nanotubes: Exchange effects and universality
Leonhard Mayrhofer, Milena Grifoni
The low energy spectrum of finite size metallic single-walled carbon nanotubes SWNTs) is determined. Starting from a tight binding model for the electrons, we derive the lo…
Quantum dissipative Rashba spin ratchets
Sergey Smirnov, Dario Bercioux, Milena Grifoni +1
We predict the possibility to generate a finite stationary spin current by applying an unbiased ac driving to a quasi-one-dimensional asymmetric periodic structure with Rashba spin…
