spin Orbit Interaction activated interchannel coupling in dipole and quadrupole photoionization
Physical Review A, 2009Co-Authors: Sunil Kumar, Tathagata Banerjee, P C Deshmukh, Steven T MansonAbstract:The effect of spin-Orbit Interaction activated interchannel coupling in dipole and quadrupole photoionization of the 4p and 4d subshells of Xe and the 5p and 5d subshells of Rn using the relativistic random phase approximation RRPA is studied. Interference between channels arising from spin-Orbit split components is found to influence the dipole cross sections of Xe 4d and Rn 5d subshells, and also the quadrupole cross sections of Xe 4p and Rn 5p subshells. The photoelectron angular distribution parameters are also affected, but to a lesser extent. Using the understanding gained, the conditions required for large spin-Orbit Interaction activated interchannel coupling effects are delineated.

spin Orbit Interaction in a two dimensional electron gas in a inas alsb quantum well with gate controlled electron density
Physical Review B, 1998Co-Authors: J P Heida, J J Kuipers, T M Klapwijk, B J Van Wees, Gustaaf BorghsAbstract:We present experiments on the tuning of the spin-Orbit Interaction in a two-dimensional electron gas in an asymmetric InAs/AlSb quantum well using a gate. The observed dependence of the spin splitting energy on the electron density can be attributed solely to the change in the Fermi wave vector. The spin-Orbit Interaction parameter $(\ensuremath{\alpha}\ensuremath{\approx}0.6\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}11}\mathrm{eV}\mathrm{}\mathrm{m})$ as such does not change significantly with electron density.

all electrical detection of the relative strength of rashba and dresselhaus spin Orbit Interaction in quantum wires
Physical Review Letters, 2008Co-Authors: Matthias Scheid, Makoto Kohda, Yoji Kunihashi, Klaus Richter, Junsaku NittaAbstract:We propose a method to determine the relative strength of Rashba and Dresselhaus spin-Orbit Interaction from transport measurements without the need of fitting parameters. To this end, we make use of the conductance anisotropy in narrow quantum wires with respect to the directions of an in-plane magnetic field, the quantum wire, and the crystal orientation. We support our proposal by numerical calculations of the conductance of quantum wires based on the Landauer formalism which show the applicability of the method to a wide range of parameters.

gate control of spin Orbit Interaction in an inverted in0 53ga0 47as in0 52al0 48as heterostructure
Physical Review Letters, 1997Co-Authors: Junsaku Nitta, Tatsushi Akazaki, Hideaki Takayanagi, T EnokiAbstract:We have confirmed that a spin-Orbit Interaction in an inverted I${\mathrm{n}}_{0.53}$G${\mathrm{a}}_{0.47}$As/I${\mathrm{n}}_{0.52}$A${\mathrm{l}}_{0.48}$As quantum well can be controlled by applying a gate voltage. This result shows that the spin-Orbit Interaction of a two-dimensional electron gas depends on the surface electric field. The dominant mechanism for the change in the spin-Orbit Interaction parameter can be attributed to the Rashba term. This inverted I${\mathrm{n}}_{0.53}$G${\mathrm{a}}_{0.47}$As/I${\mathrm{n}}_{0.52}$A${\mathrm{l}}_{0.48}$As heterostructure is one of the promising materials for the spin-polarized field effect transistor which is proposed by Datta and Das [Appl. Phys. Lett. 56, 665 (1990)].

one dimensional ring in the presence of rashba spin Orbit Interaction derivation of the correct hamiltonian
Physical Review B, 2002Co-Authors: F E Meijer, Alberto F Morpurgo, T M KlapwijkAbstract:We describe in detail the procedure for obtaining the correct one-dimensional Hamiltonian of electrons moving on a ring in the presence of Rashba spin-Orbit Interaction. The subtlety of this seemingly trivial problem has not been fully appreciated so far and it has led to some ambiguities in the existing literature. Our work illustrates the origin of these ambiguities and solves them.
