Spin orientation and spin-Hall effect induced by tunneling electrons
A. G. Mal'shukov, C. S. Chu
It is shown that a flux of unpolarized electrons across a symmetric double barrier quantum well induces a spin polarization inside the well. Besides, the transmitted current acquir…
Low-frequency spectroscopy of superconducting photonic crystals
A. N. Poddubny, E. L. Ivchenko, Yu. E. Lozovik
Transmission, reflection and absorption of electromagnetic radiation and photon dispersion law for 2D photonic crystals with superconducting elements are studied. The calculation o…
Spin Injection in Quantum Wells with Spatially Dependent Rashba Interaction
Arne Brataas, A. G. Mal'shukov, Yaroslav Tserkovnyak
We consider Rashba spin-orbit effects on spin transport driven by an electric field in semiconductor quantum wells. We derive spin diffusion equations that are valid when the mean…
Quantum Dot Version of Berry's Phase: Half-Integer Orbital Angular Momenta
V. D. Mur, N. B. Narozhny, A. N. Petrosyan +1
We show that Berry's geometrical (topological) phase for circular quantum dots with an odd number of electrons is equal to πand that eigenvalues of the orbital angular momentum run…
Universality in scattering by large-scale potential fluctuations in two-dimensional conductors
Vladimir I. Yudson, Dmitrii L. Maslov
We study electron propagation through a random array of rare, opaque and large (compared the de Broglie wavelength of electrons) scatterers. It is shown that for any convex scatter…
