Spin-orbit induced spin-qubit control in nanowires
Christian Flindt, Anders S. Sorensen, Karsten Flensberg
We elaborate on a number of issues concerning our recent proposal for spin-qubit manipulation in nanowires using the spin-orbit coupling. We discuss the experimental status and des…
Mass and charge transport in micro and nano-fluidic channels
N. A. Mortensen, L. H. Olesen, F. Okkels +1
We consider laminar flow of incompressible electrolytes in long, straight channels driven by pressure and electro-osmosis. We use a Hilbert space eigenfunction expansion to address…
Highly dispersive photonic band-gap-edge optofluidic biosensors
Sanshui Xiao, Niels Asger Mortensen
Highly dispersive photonic band-gap-edge optofluidic biosensors are studied theoretically. We demonstrate that these structures are strongly sensitive to the refractive index of th…
Inelastic transport theory from first-principles: methodology and applications for nanoscale devices
Thomas Frederiksen, Magnus Paulsson, Mads Brandbyge +1
We describe a first-principles method for calculating electronic structure, vibrational modes and frequencies, electron-phonon couplings, and inelastic electron transport propertie…
Selective lasing in multimode periodic and non-periodic nanopillar waveguides
S. V. Zhukovsky, D. N. Chigrin, A. V. Lavrinenko +1
We investigate the lasing action in coupled multi-row nanopillar waveguides of periodic or fractal structure using the finite difference time domain (FDTD) method, coupled to the l…
Different quantization mechanisms in single-electron pumps driven by surface acoustic waves
P. Utko, K. Gloos, J. Bindslev Hansen +2
We have studied the acoustoelectric current in single-electron pumps driven by surface acoustic waves. We have found that in certain parameter ranges two different sets of quantize…
